  • the present invention speeds the transmission and processing of data objects which incorporate other data objects by reference. More specifically, the present invention improves the performance of web servers, web caches and web browsers by repackaging existing HTML web page content for more efficient transport over the Internet using existing HTTP and TCP/IP facilities.
  • means are employed on the server-side of the HTTP link for packaging coherency information for a given data object, such as an HTML web page or an XML document, together with coherency information describing the state of entities referenced in that page or document, so that the combined coherency information is sent to the client as a single object in a single HTTP request-response exchange.
  • the received object is interpreted to avoid the needless transmission of further HTTP requests when valid copies ofreferenced entities already exist in the local cache.
  • means are employed on the server side for packaging the content of a given data object, such as an HTML web page or an XML document, together with content obtained from external resources referenced in that page or document, allowing the combined content to be transferred as a single object to the client.
  • a given data object such as an HTML web page or an XML document
  • the single received object is decomposed into its constituent parts which are may be rendered or processed without the need for further network transfers.
  • the client-side of an HTTP link may advantageously employ conventional web browsers, XML processors or other existing programs which are used in combination with an auxiliary program (e.g.
  • client side applications such as web browsers, may be modified to incorporate the functionality needed to directly request and handle the more concise combined objects contemplated by the invention.
  • means are employed at the server for processing data objects which incorporate other data objects by reference to create combined data objects for transmission to requesting clients.
  • a server-side program may be employed to process HTML web pages to create new combined data objects which include referenced data and which are requested by client side programs capable of processing those combined objects.
  • Each such combined object provides the coherency data and content required to render an entire web page. Because these combined documents need be created only once, they can be built and stored asynchronous with the client requests and do not require significant server-side CPU resources.
  • the principles of the invention may be applied to improve the performance of Dynamic HTML (DHTML) web pages, including both Active Server Pages (ASP) and pages generated by Common Gateway Interface (CGI) programs.
  • the invention may be used to implement a "delta cache" in which only the changed portions of modified programs or files need be sent from te server to the client, and for managing cache coherency by the use of unambiguous entity references.
  • the principles of the present invention may be applied to advantage to eliminate unnecessary network request-response exchanges when valid copies of information included by reference in a given web page or XML document is already present in the local cache at the client.
  • a web browser user clicks on a link to the URL "foo.htm” the browser issues an HTTP GET request for "foo.htm”.
  • the client side program intercepts the request and instead issues a request to the web server for a combined object named "oc_foo.htm.”
  • the object named "oc_foo.htm” may be produced by a server side program which combines foo.htm and other data objects which are to be included by reference in the rendered version offoo.htm.
  • the combined object "oc_foo.htm” contains coherency data for foo.htm and for the other objects referenced by foo.htm.
  • the client program receives coherency information on all of the included objects in a single message exchange, eliminating the need for further exchanges to determine whether valid copies of the referenced objects are already present in the cache.
  • object packing is employed to efficiently transport data objects between the ICDS client and the ICDS server.
  • each object required to render a web page must be individually requested by the browser and sent separately to the client by the web server; and each request is burdened by the overhead of the verbose HTTP protocol and latency of the Internet.
  • server-side routines may be executed to pre-processes the
  • HTML web page combining the web page HTML with the content of data objects referenced by HTML tags, to form a combined object (e.g; a single file having its own URL) which includes a directory of offsets to the individual files objects contained within the combined object.
  • the referenced objects included in the combined file may comprise image, applet or other HTML files specified in ⁇ OBJECT>, ⁇ IMG> , ⁇ APPLET>, ⁇ FRAME> or ⁇ IFRAME> tags.
  • the number of HTTP requests transmitted to the server is reduced, reducing the burden on the client, the server and on the network, and the cumulative delay caused by Internet latency is reduced since the number of Internet exchanges needed to display a given web page is reduced, regardless of whether or not that valid copies of that page and its referenced objects are present in the local cache.
  • HTTP 1.1 which permits the transfer of designated file ranges may be used to advantage.
  • the HTTP 1.1 protocol allows multiple designated ranges to be requested and transferred in a single request.
  • Additional logic on the client-side and the server-side may be employed to optimize web page content delivery based on the current connection speed between the web browser and web server. For example, different classes of clients may issue requests for objects specifically optimized for those devices. For example, an object ID value may be transferred with the request which has one the values listed below:
  • Web content may accordingly be pre-processed by the server-side routines which bind the constituent parts of web pages and referenced objects into combined objects that are optimized for particular client devices and which can be requested by these devices based on their connection speed and other criteria.
  • the optimization of the transport process is transparent to the web page designers who may focus on the graphical content of the web site independent of the delivery speed over a wide range of connection speeds
  • the same technique can be used for adding additional capabilities including automatic language translation based on the clients requested language preference.
  • DHTML server-side Dynamic HTML
  • Common applications for DHTML include customizing web pages to include current information (date/news/events) often driven by a database back-end.
  • DHTML is also commonly used to provide HTML page responses for search engines and e-commerce order processing.
  • a transparent mechanism may be employed to separate the static from the dynamic elements such that only the dynamic elements need be retrieved.
  • Active Server Pages extends HTML to include tags that are redirected by the web server to an ASP process to convert the ASP requests into the desired HTML code. The browser only sees the resultant HTML code, not the ASP calls.
  • Active Server Pages may be pre-processed to separate the active from the static elements on those pages. As a consequence, the server does not does not require an active process running on the web server to obtain the advantages of the invention. An example of the approach used is detailed below:
  • OC client intercepts original request and instead requests OC somefilel.ASP from the web server OC somefilel.asp contains coherency data for all objects including OC_Static_somefilel.asp )
  • OC client merges dynamic content returned from the server with static content from local cache to produce the dynamic HTML page to the browser. (Also marked as uncacheable to the browsers cache as it would have been in the original request.)
  • client side program responds to the original browser request for somefilel .asp and passes back the header information received from the server for OC Dynamic somefilel. asp
  • ASP Active Server Pages
  • CGI Common Gateway Interface
  • HTML implemented-using CGI HTML implemented-using CGI.
  • an active process running on the web server is employed to intercept the HTML stream. This process parses the outgoing HTML stream and optimizes the information for transport over the Internet.
  • all of the objects referenced by the CGI generated HTML page can be checked for coherency with a single request and all of the data objects referenced by the CGI-generated HTML page can also be transferred in response to a single request. There is no compromise of coherency, and the need for multiple coherency checks and data - transfers of the static elements referenced on the CGI-generated pages is eliminated. Implementation of a "Delta Cache"
  • client-side HTML code execution is that the client can do local processing and be more insulated from the web server/internet.
  • the problem is that, as the programs transmitted for execution on the client get larger, even small changes to the program file require the entire file to be resent to the client.
  • delta caching routines proceed as follows:
  • Browser requests foo.htm from web server 2.
  • a client routine requests OC_foo.htm from web server
  • the file oc_foo.htm contains coherency data for foo.htm and the objects referenced by foo.htm including the availability of delta objects.
  • a client routine determines that foo.htm or some other object referenced on the page and available in the client cache has changed 5.
  • a client routine requests a combined object with delta changes
  • a client routine returns whole object with the delta changes to the browser
  • a global object store may be employed to solve one of the fundamental problems inherent in the manner in which information is currently distributed over the Internet.
  • Theis problem stems from the ambiguous references which may be used by HTML to identify external entities which are to be included with the page. These ambiguous references require the browser to send additional requests to the server to determine if each file in the browser cache is the same as the file on the server. It should be noted that ambiguous references are a common problem that plagues web caches, wasting bandwidth by requiring continuous checking for newer version of each file on the web server.
  • ambiguous file references are converted into non- ambiguous references by including the file coherency information as an integral part of the file name. Take for example a web page that references two graphics file bannerl .gif and banner2.gif.
  • the file directory information shown above is automatically processed to rename the files as GOS_S980804122217_bannerl .gif and GOS_990515090713_banner2.gif respectively, all HTML references to these files are changed to use the new names, the files are tagged as expiring 100 years from the processing date. As a consequence, if the web browser or web cache locates the file, it is by definition coherent and no further checks are required. Marking the file as expiring in 100 years makes use of a built in capability of HTTP that has long been underutilized.
  • the accompanying Appendix contains source language listings of Java programs which implement some of the features of the invention as described above and which have been developed using the Visual Cafe Java development environment supplied by Symantec Corporation of Cupertino, CA.

Abstract

A system for increasing the speed of transmission and processing of hypertext data objects, such as HTML web pages and XML documents, that incorporate external data objects by reference, by repackaging existing HTML and XML content and coherency information for more efficient transport over the Internet using existing HTTP and TCP/IP facilities. At the server side of an HTTP link, the content of a hypertext data object is repackaged and renamed as a compound data object which includes data and/or coherency information for imbedded data objects whose URLs are specified in the hypertext object. On the client side, the received compound object is interpreted to avoid the needless transmission of further HTTP requests when valid copies of referenced entities already exist in the local cache, and to obtain the content of the hypertext data object as well as the content of one or more referenced objects in a single request-response interchange. The Appendix contains a Java code implementation of some of the features disclosed.

Storing, Retrieving and Manipulating Hypertext Data
Applicant: WWWhoosh, Inc. 160 Old Maple Street Stoughton, MA 02072 U.S.A.
Inventor: Clinton Brenton Battersby 64 Laurelwood Dr. Stoughton, MA 02072 U.S.A.
Technical Field
This invention relates to hypertext communication systems and more particularly to methods and apparatus for speeding the transmission of data objects which incorporate other data objects by reference.
Background Art
The present invention may be used to advantage to more rapidly transmit the information needed for displaying web pages expressed in Hypertext Markup Language (HTML) by means of the Hypertext Transfer Protocol (HTTP). The principles of the invention may also be employed for displaying or processing other forms of information, such as data expressed in SGML and XML which, like HTML, employ data objects which incorporate information found in separate resources which are specified by an suitable identifier, such as an Internet URL, and retrieved using the a suitable request-response network communications protocol, such as the conventional HTTP / TCP-IP transmission mechanism used by the Internet World Wide Web facility.
HTML and XML HTML, in its preferred forms, as been defined in specifications which have continued to evolve to meet needs of users and developers. HTML 2.0 was developed under the aegis of the Internet Engineering Task Force (IETF) to codify common practice in late 1994 and is described in RFC 1866 (November, 1995). The efforts of the World Wide Web Consortium's HTML Working Group to codify common practice in 1996 resulted in HTML 3.2 (January 1997). HTML 4.0, the latest version of which is available at the URL http://www.w3.org/TR/html40, extends HTML with mechanisms for style sheets, scripting, frames, embedding objects, and other enhancements. HTML's multimedia features allow authors to include images, applets (programs that are automatically downloaded and run on the user' s machine), video clips, and other HTML documents in their pages. Commonly, in order to completely render a web page (i.e, to display all of the referenced text and images, as well as to play referenced sound and/or video files), it is necessary for the web browser program to scan the HTML text, identify the references to included resources that need to be fetched, and issue a sequence of separate requests using the Hypertext Transfer Protocol (HTTP) to obtain a current copy of each additional item ofreferenced data. The Extensible Markup Language (XML) is a subset of SGML which was designed to enable generic SGML to be served, received, and processed on the Web in the way that was previously possible with HTML. An XML document, as specified in the World Wide Web Consortium' s Recommendation entitled "Extensible Markup Language (XML) 1.0" (February, 1998), may consist of one or many storage units called entities; all of which have content and which are typically identified by name. Each XML document has one entity called the document entity, which serves as the starting point for the XML processor and may contain the whole document. The XML specification permits an XML document to refer to one or more external entities by an appropriate identifier (URI) so that the content of the external entity referred to may be incorporated into the XML document. Thus, like an HTML web page, the validation or processing of an XML document may require multiple HTTP request/response exchanges to assemble the entire document.
HTTP and Caching
Versions 1.0 and 1.1 of the Hypertext Transfer Protocol (HTTP) are defined and described by theTnternet Engineering Task Force (IETF) Request for Comment (RFC) 1945 by T. Berners-Lee, R. Fielding and H. Frystyk entitled "Hypertext Transfer Protocol ~ HTTP/1.0", May, 1996 and in RFC 2068 by R. Fielding, J. Gettys, J. C. Mogul, H. Frystyk and T. Berners-Lee entitled "Hypertext Transfer Protocol ~ HTTP/1.1 ", January, 1997. Significant work has been done at the IETF as the HTTP protocol has evolved over the last 5 years from V1.0 to Vl.l recently adopted as the new standard. HTTP 1.1 has incorporated a number of enhancements to improve browser to web server and browser to web cache performance. The standard has historically and will continue to evolve at a necessarily slow pace to accommodate the millions of devices using the protocols to guarantee a smooth integration of the new capabilities. As noted above, HTML pages and XML documents often reference one or more external entities which are separate physical storage objects and which much be fetched via the communications network in order to render or process the entire page or document. Because these external objects are frequently re-used by client applications, caching may be used to advantage. Historically, web browsers send multiple HTTP GET requests with the "If Modified- Since" extension to validate the current contents of the cache (local storage space holding recently fetched files for immediate recall). If the object in the local cache is still valid, the server responds with a "304" response directing the client application to use the local copy in the cache. If the content is not the same, the server returns a fresh copy of the data. The following text illustrates the verbose exchange required to retrieve a single external storage object using HTTP.

This lengthy exchange must be repeated for each object on the HTML page, even when those external files are already available on the local cache.
Description of the Best Mode
The present invention speeds the transmission and processing of data objects which incorporate other data objects by reference. More specifically, the present invention improves the performance of web servers, web caches and web browsers by repackaging existing HTML web page content for more efficient transport over the Internet using existing HTTP and TCP/IP facilities.
As contemplated by a first aspect of the present invention, means are employed on the server-side of the HTTP link for packaging coherency information for a given data object, such as an HTML web page or an XML document, together with coherency information describing the state of entities referenced in that page or document, so that the combined coherency information is sent to the client as a single object in a single HTTP request-response exchange. On the client side, the received object is interpreted to avoid the needless transmission of further HTTP requests when valid copies ofreferenced entities already exist in the local cache.
In accordance with another feature of the invention, means are employed on the server side for packaging the content of a given data object, such as an HTML web page or an XML document, together with content obtained from external resources referenced in that page or document, allowing the combined content to be transferred as a single object to the client. On the client side, the single received object is decomposed into its constituent parts which are may be rendered or processed without the need for further network transfers. As contemplated by the invention, the client-side of an HTTP link may advantageously employ conventional web browsers, XML processors or other existing programs which are used in combination with an auxiliary program (e.g. a plug-in, helper, or proxy program) which acts as a transport layer between the HTTP interface and the application program, capturing and converting outbound HTTP requests from the application program into requests for more concise objects, and for intercepting the incoming concise objects which are supplied by the server and translating them into the multiple data objects originally requested by the application program. Alternatively, client side applications, such as web browsers, may be modified to incorporate the functionality needed to directly request and handle the more concise combined objects contemplated by the invention.
In accordance with another aspect of the invention, means are employed at the server for processing data objects which incorporate other data objects by reference to create combined data objects for transmission to requesting clients. For example, a server-side program may be employed to process HTML web pages to create new combined data objects which include referenced data and which are requested by client side programs capable of processing those combined objects. Each such combined object provides the coherency data and content required to render an entire web page. Because these combined documents need be created only once, they can be built and stored asynchronous with the client requests and do not require significant server-side CPU resources. In accordance with still further features of the invention, described in more detail below, the principles of the invention may be applied to improve the performance of Dynamic HTML (DHTML) web pages, including both Active Server Pages (ASP) and pages generated by Common Gateway Interface (CGI) programs. In addition, the invention may be used to implement a "delta cache" in which only the changed portions of modified programs or files need be sent from te server to the client, and for managing cache coherency by the use of unambiguous entity references.
These and other objects, features and advantages of the invention may be more fully understood through a consideration of the following detailed description.
Detailed Description
Minimizing Cache Coherency Traffic
The principles of the present invention may be applied to advantage to eliminate unnecessary network request-response exchanges when valid copies of information included by reference in a given web page or XML document is already present in the local cache at the client. By way of example, if a web browser user clicks on a link to the URL "foo.htm", the browser issues an HTTP GET request for "foo.htm". Before the request is sent to the server, however, the client side program intercepts the request and instead issues a request to the web server for a combined object named "oc_foo.htm." The object named "oc_foo.htm" may be produced by a server side program which combines foo.htm and other data objects which are to be included by reference in the rendered version offoo.htm. The combined object "oc_foo.htm" contains coherency data for foo.htm and for the other objects referenced by foo.htm. As a consequence, the client program receives coherency information on all of the included objects in a single message exchange, eliminating the need for further exchanges to determine whether valid copies of the referenced objects are already present in the cache.
Increasing Efficiency by Combining Content According to a further feature of the invention, object packing is employed to efficiently transport data objects between the ICDS client and the ICDS server. Under conventional practice, each object required to render a web page must be individually requested by the browser and sent separately to the client by the web server; and each request is burdened by the overhead of the verbose HTTP protocol and latency of the Internet. As contemplated by the invention, server-side routines may be executed to pre-processes the
HTML web page, combining the web page HTML with the content of data objects referenced by HTML tags, to form a combined object (e.g; a single file having its own URL) which includes a directory of offsets to the individual files objects contained within the combined object. The referenced objects included in the combined file may comprise image, applet or other HTML files specified in <OBJECT>, <IMG> , <APPLET>, <FRAME> or <IFRAME> tags.
There are a number of benefits in the combined packaging of content and coherency information as contemplated by the invention: the number of HTTP requests transmitted to the server is reduced, reducing the burden on the client, the server and on the network, and the cumulative delay caused by Internet latency is reduced since the number of Internet exchanges needed to display a given web page is reduced, regardless of whether or not that valid copies of that page and its referenced objects are present in the local cache.
If the browser already has some or many of the objects in the local cache, it would be a waste of time and bandwidth to transfer the entire combined object to get the required objects. In accordance with another feature of the invention, a feature of HTTP 1.1 which permits the transfer of designated file ranges may be used to advantage. The HTTP 1.1 protocol allows multiple designated ranges to be requested and transferred in a single request. As a consequence, when a combined coherency check indicates that the local cache can satisfy some, but not all of the individual object requests, the objects which are still needed can be compiled into a compound request for objects not in the local cache.
It should also be noted that the combined objects created in accordance with this invention may be transmitted in a sequence of blocks sized to optimize network performance. Optimization
Additional logic on the client-side and the server-side may be employed to optimize web page content delivery based on the current connection speed between the web browser and web server. For example, different classes of clients may issue requests for objects specifically optimized for those devices. For example, an object ID value may be transferred with the request which has one the values listed below:
OCD_ - ICDS-2 Meta Object (No optimization)
OCD14_ - Optimized for 14.4 connections
OCD28_ - Optimized for 28.8 connections OCD56_ - Optimized for 56K connections
OCDTl_ - Optimized for high speed Tl connections
OCDTV_ - Optimized for Web TV Delivery
OCDPDA_ - Optimized for PDA / Cell browsing
Web content may accordingly be pre-processed by the server-side routines which bind the constituent parts of web pages and referenced objects into combined objects that are optimized for particular client devices and which can be requested by these devices based on their connection speed and other criteria. The optimization of the transport process is transparent to the web page designers who may focus on the graphical content of the web site independent of the delivery speed over a wide range of connection speeds The same technique can be used for adding additional capabilities including automatic language translation based on the clients requested language preference.
Dynamic Web Content
There are a number of technologies collectively called server-side Dynamic HTML (DHTML) that provide facilities for dynamic rather than static responses to a browser request. Common applications for DHTML include customizing web pages to include current information (date/news/events) often driven by a database back-end. DHTML is also commonly used to provide HTML page responses for search engines and e-commerce order processing.
In many applications only a small percentage of the DHTML generated by the server changes but the entire page must be retransmitted. (By definition, Dynamic HTML pages are not given modified dates and cannot be cached.) As contemplated by a further feature of the invention, a transparent mechanism may be employed to separate the static from the dynamic elements such that only the dynamic elements need be retrieved.
Active Server Pages (ASP) One popular type of Dynamic HTML, introduced by Microsoft, takes the form of
Active Server Pages (ASP). ASP extends HTML to include tags that are redirected by the web server to an ASP process to convert the ASP requests into the desired HTML code. The browser only sees the resultant HTML code, not the ASP calls. As contemplated by the invention, Active Server Pages may be pre-processed to separate the active from the static elements on those pages. As a consequence, the server does not does not require an active process running on the web server to obtain the advantages of the invention. An example of the approach used is detailed below:
On the ASP server side: 1. A server program processes a static distribution of somefilel .ASP Create
OC somefilel.asp including the last modified date of any other objects used to render the page.
2. Create OC_Static_somefile 1.asp with #lnclude_001 , #Include_002 tags to replace the ASP calls.
Static Html Static Html <!-- #Include_001~> 30 Static HTML Static HTML <!-- #Include_002-> Static HTML Static HTML
3. Create OC Dynamic somefilel .asp file with identifying tags and the ASP calls
<!-- #Include_001 Start-> ASP CODE ASP CODE 10 ASP CODE
<!-- #Include_001 End->
<!-- #Include_002 Start-> ASP CODE 15 ASP CODE ASP CODE <!-- #Include_002 End->
On the client side:
1. Browser requests somefilel .asp (No modified date because it was uncacheable)
2. OC client intercepts original request and instead requests OC somefilel.ASP from the web server OC somefilel.asp contains coherency data for all objects including OC_Static_somefilel.asp )
3. If OC Static somefile 1.asp not in cache or not current, get
OC_Static_somefilel .asp
4. Request OC Dynamic somefilel .asp from server (Never in local cache)
5. OC client merges dynamic content returned from the server with static content from local cache to produce the dynamic HTML page to the browser. (Also marked as uncacheable to the browsers cache as it would have been in the original request.)
6. Note that the client side program responds to the original browser request for somefilel .asp and passes back the header information received from the server for OC Dynamic somefilel. asp
The use of the invention in connection with Active Server Pages (ASP) reduces the majority of the bytes necessary to refresh an ASP page because only the dynamic portions are actually transmitted between the server and the browser. There is no compromise of coherency. The redundant transfer of the static elements on ASP pages is eliminated, and no active process is required on the web server.
CGI Based Dynamic HTML An earlier and still popular method for creating dynamic HTML pages is to use the
Common Gateway Interface (CGI). CGI provides a standard way to execute programs on the web server to generate dynamic HTML code. CGI is very different from ASP because 1) the web server does not have access to the CGI application source code and 2) there are no standards for the actual code being run using the CGI interface. Nonetheless, the present invention can be used to advantage in connection with dynamic
HTML implemented-using CGI. To do so, an active process running on the web server is employed to intercept the HTML stream. This process parses the outgoing HTML stream and optimizes the information for transport over the Internet. By using the invention in connection with CGI processing, all of the objects referenced by the CGI generated HTML page can be checked for coherency with a single request and all of the data objects referenced by the CGI-generated HTML page can also be transferred in response to a single request. There is no compromise of coherency, and the need for multiple coherency checks and data - transfers of the static elements referenced on the CGI-generated pages is eliminated. Implementation of a "Delta Cache"
Problems that can occur when more functionality is pushed down to the browser using client-side dynamic HTML. The advantage of client-side HTML code execution is that the client can do local processing and be more insulated from the web server/internet. The problem is that, as the programs transmitted for execution on the client get larger, even small changes to the program file require the entire file to be resent to the client.
As contemplated by the invention, this problem may be addressed by allowing the client to request the changes to a file instead of the entire file. On the server side, routines are provided which enable the server to identify those objects which may benefit significantly from using a delta cache, and "delta object" are only generated when a significant benefit (say, greater than a 70% saving) may be expected. On the client side, delta caching routines proceed as follows:
1. Browser requests foo.htm from web server 2. A client routine requests OC_foo.htm from web server
3. The file oc_foo.htm, contains coherency data for foo.htm and the objects referenced by foo.htm including the availability of delta objects.
4. A client routine determines that foo.htm or some other object referenced on the page and available in the client cache has changed 5. A client routine requests a combined object with delta changes
6. A client routine returns whole object with the delta changes to the browser
7. And the process is repeated for the other objects.
A Global Object Store
As contemplated by still another feature of the invention, a global object store may be employed to solve one of the fundamental problems inherent in the manner in which information is currently distributed over the Internet. Theis problem stems from the ambiguous references which may be used by HTML to identify external entities which are to be included with the page. These ambiguous references require the browser to send additional requests to the server to determine if each file in the browser cache is the same as the file on the server. It should be noted that ambiguous references are a common problem that plagues web caches, wasting bandwidth by requiring continuous checking for newer version of each file on the web server.
Although the use of the coherency checking mechanism described above keeps redundant requests for coherency from propagating over the Internet, a further feature of the invention may be employed to reduce the processing overhead-itself. In accordance with this aspect of the invention, ambiguous file references are converted into non- ambiguous references by including the file coherency information as an integral part of the file name. Take for example a web page that references two graphics file bannerl .gif and banner2.gif.
bannerl.gif 04/08/98 12:22:17
20 banner2.gif 05/15/99 09:07:13
To eliminate the ambiguous file reference problem, -the file directory information shown above is automatically processed to rename the files as GOS_S980804122217_bannerl .gif and GOS_990515090713_banner2.gif respectively, all HTML references to these files are changed to use the new names, the files are tagged as expiring 100 years from the processing date. As a consequence, if the web browser or web cache locates the file, it is by definition coherent and no further checks are required. Marking the file as expiring in 100 years makes use of a built in capability of HTTP that has long been underutilized.
Accompanying Source Code
The accompanying Appendix contains source language listings of Java programs which implement some of the features of the invention as described above and which have been developed using the Visual Cafe Java development environment supplied by Symantec Corporation of Cupertino, CA. In the Appendix, the Java class listings for the client side application are presented first, followed by the classes for the server side application, and concluding with common classes shared by both.
Conclusion
It is to be understood that the methods which have been described are merely illustrative applications of the principles of the invention. Numerous modifications may be made without departing from the true spirit and scope of the invention.

// aversion 1.0 support version mfo in header, compression optional
// aversion 2.0 support incremental updates
//
//
// Modifications:
//
//
// This class is responsible for taking an input directory or file spec and outputtmg
// OC and OCD files for it. It interacts with the GUI and Config classes to decide
// how much to do. The Optimizer is a Thread so it can be stopped/started by GUI
// Button callbacks running m the main thread.
//
// BUILD DATE COMMENTS
//
// 746 4-Aug-99
//
// 1- buttons reworked to be better placed and uniform sizes
//
// 2- error messages made more uniform (case and severity levels)
//
// 3- STOP button message changed -
// changed the message so it says "Finishing current input" as
// soon as you hit the button, then "Generation Halted" is printed
// after the current input is done processing.
//
// 4- changed domain root specification to use browse field
//
//
// 13-Aug-99 More GUI refinement:
// made some dialogs modal
// moved buttons off panels
// set -noresize
//
// 14-Aug-99 performance issues - initialization time
//
// 18-Aug-99 rework logging, add -append
//
// 19-Aug-99 create/integrate FileFormatMgr class to write header
// mfo before OC and OCD mfo
//
// 30-Aug-99 add dialog to save changes on input dialog close, fix logging bug
// consolidate WhooshHeader class - common across client and server
//
// l-Sep-99 move
// Incremental updates: generate OC BEFORE OCD, and compare all timestamps.
// if none have changed, skip writing OC and generating OCD
//
// 2-Sep-99 renamed all classes and vars and labels from ICDS to WWWhoosh

Claims

What is claimed is:
1. The method for processing and transmitting a hypertext data object which comprises, in combination, the steps of: at an Internet server location: scanning the content of a given hypertext data object to identify at least one external data object that is referred to in said hypertext data object, combining said given hypertext data object and said external data object to form a single compound object containing data from said hypertext data object and said external data object, and assigning a unique resource name to said compound object which is derived from the resource name of said given hypertext data object, at an Internet client location: deriving said unique resource name from said resource name of said given hypertext data object, transmitting a request for said single compound data object specified by said unique resource name to said server location, receiving said single compound data object when from said server location in response to said request, and processing said compound data object to render said hypertext data object and said external data object at said client location, whereby the data needed to render said hypertext data object is obtained in a single request-response transaction rather than a plurality of request-response transactions.
2. The method of avoiding unnecessary network request-response exchanges when valid copies of information included by reference in a hypertext data object is already stored in the local cache at a client location, said method comprising, in combination, the steps of: at an Internet server location: analyzing the content of a given hypertext data object to identify at least one external data object that is referred to in said hypertext data object, forming a single compound data object which contains information describing said given hypertext data object and information describing the time at when said external data object was last modified at said server location, and transmitting said single compound data object from said server location to said client location, and at said client location, receiving said compound data object from said server location, and comparing said information describing the time when said external data object was last modified at said server location with the time when a copy of said external data object was last stored in said local cache.
