Year CERN (European Laboratory for Particle Phys
ics) is a distributed information system based on the concept of hypertext proposed by Tim Berners-Lee et al. In this method, various objects (texts, images, sounds, moving images, etc.) distributed on the Internet are regarded as hypertexts, and users can use the information with uniform operability.
The WWW client has a unified GUI, and the user simply points to a hyperlink (called an anchor, with text or icons highlighted,
With just a click of the mouse (displayed in a different color than the whole), you can extract information distributed on the Internet.

[0003] In the WWW technology, a URL (Uniform Resource L) indicating a place where an object exists or an access method is used.
ocator) (RFC1738), HTML (Hiper Text Markup Language) that describes information as hypertext (RFC18)
66), the protocol HTT ((Hiper
Text Transfer Protocol (RFC1630), a WWW client that extracts information, and a WWW server that provides information.

Here, a conventional WWW server system will be described with reference to FIG.

Next, the configuration of the "object storage tables" 123a and 133a of the first embodiment will be described with reference to FIG.

FIG. 4 is a diagram showing the structure of the "object storage table" according to the first embodiment of the present invention.

As shown in FIG. 4, the "object storage table" includes items such as "URL", "last access date and time", "storage period", and "pointing to object".
Consists of

The object requested to be accessed by the WWW client is read from the external storage device and registered in the "object storage table". Further, when an access request is made from the WWW client, if the object is already registered in the “object storage table”, reading from the external storage device is not performed, and the registered object is used. Among the items of the "object storage table", the "last access date" sets the object in the "object storage table" and updates the object every time there is an access request from the WWW client.

The "storage period" of the items in the "object storage table" determines the timing of deleting objects that are no longer used or hardly used from the "object storage table". Is provided for use as an indicator for The “accumulation period” is a predetermined procedure, for example, W
It is assumed that it has already been set in the configuration file of the WW server. Further, the deletion of the object is performed by an object deletion unit 146 (the flowchart of FIG. 6) described later. In the first embodiment, the object is deleted when the processing date and time exceeds “last access date and time + accumulation period”. . For example, “doc1.h” in FIG.
“tml” is deleted by the object deletion unit 146 after 13:00 on 1996/12/20.

Next, the processing executed in the first embodiment will be described with reference to FIGS. FIG. 5 and FIG. 6 are flowcharts showing processing executed in the first embodiment of the present invention.

FIG. 5 shows the processing operation from the object reading section 141 to the object prefetching section 145, and FIG. 6 shows the processing of the object deleting section 146. The processing described with reference to FIG. 5 is implemented as a part of the mechanism of the WWW server system.

First, when the WWW server 131 is started, a predetermined initial process is performed, and then in step S201,
It is determined whether there is a processing request from the WWW client 111. If there is no processing request from the WWW client 111 (NO in step S201), the process waits until there is a request. On the other hand, if there is a processing request from the WWW client 111 (YES in step S201), the process proceeds to step S202.

In step S202, the contents of the processing request are analyzed. In step S203, it is determined whether or not the processing request is a request for an object on the WWW server 131. If not an object request (step S20)
(NO in 3), the process proceeds to step S204, and other processes are performed. Since this processing is within the scope of the present invention, it is not particularly described. On the other hand, if the request is for an object (YES in step S203), step S20
Go to 5.

In step S205, the "object storage table" 133a is searched to determine whether the requested object is stored. If it is stored (YES in step S208), step S20
Proceed to 8. On the other hand, if it is not stored (step S2
05 (NO), the process proceeds to step S206.

In step S206, the external storage device 132
Read the corresponding object from. And step S
At 207, the object is registered in the "object storage table" 133a for the next access.

In step S208, the requested object is returned to the WWW client 111. W
When the object is returned to the WWW client 111, the WWW client 111 and the WWW server 131
The connection with is disconnected. The processing of the WWW server 131 after step S209 described below is
It is executed asynchronously with the client 111. In the first embodiment, a series of processes is described in the same flowchart, but may be executed as a separate thread.

In step S209, it is analyzed whether the requested object has a link to another object. As a result of the analysis, if there is link information, the processing from step S210 is repeated until all the link information has been processed. First, step S21
At 0, it is determined whether all link information has been processed. When all link information has been processed (step S2
(YES at 10), and returns to step S201. On the other hand, if all link information has not been processed (step S21)
(0 and NO), the process proceeds to step S211.

Next, in step S211, it is determined whether or not the link destination object indicated by the unprocessed link information exists on the server. If it is on its own server (YES in step S211), the process advances to step S212 to read the corresponding object from the external storage device 132. Then, for the next access, step S21
At 3, the object is stored in the “object storage table” 1
33a. On the other hand, if the link destination object indicated by the unprocessed link information is not on the own server (NO in step S211), the process advances to step S214 to request the corresponding server to prefetch the object.

Next, a specific example of the processing described in FIG. 5 will be described with reference to FIG. Here, it is assumed that the first access from the WWW client to the WWW server, that is, nothing is registered in the “object storage table”.

In FIG. 3A, for example, the URL “http: // w
When “ww.foo.co.jp/doc1.html” is input, the WWW client 111 sends the WWW server 131 “www.foo.c
o.jp "is requested for the HTML document" doc1.html "(step S201).

When the WWW server 131 receives the request from the WWW client 111, the WWW server 131 proceeds to step S202.
After step S203, the process proceeds to step S205. Then, in step S205, the “object storage table” 133a is searched. In this case, the requested HTM
Since the L document “doc1.html” has not yet been stored in the “object storage table” 133a, step S
At 206, “doc1.html” is read from the external storage device 132. Then, for the next access, step S
In step S207, the WWW client 111 registers the information in the “object storage table” 133a.
Reply to.

After returning the requested object to the WWW client 111, the WWW server 131 determines in step S209 that the previously read HTML document “do
Analyze whether there is a link to another object in "c1.html". If there is link information, step S21 is performed until all link information has been processed.
The processing after 0 is repeated.

There are three links in the requested HTML document “doc1.html”. The first link is "<IMG
SRC = "img / star.gif">"is a link to the object on the server. The second link is "<A HREF
= "doc2.html"> link to doc2 </A>", which is also a link to the object on your server. The third link is "<A HREF =" http://www.xyz.co.jp/man1.html "
> link to man1 </A>", which is a link to an object on another server.

The object on the server, "img /
“star.gif” and “doc2.html” read the corresponding objects from the external storage device 132 in step S212. Then, for the next access, in step S213,
The object is stored in the “object storage table” 133a.
Register with. On the other hand, the object “man1.html” on another server requests the corresponding server to prefetch the object in step S214.

By the processing so far, the information as shown in FIG. 4 is registered in the “object storage table” 133a.

When the WWW client 111 receives the reply from the WWW server 131, the received HTM
Analyze the L document and format it according to HTML
The document is displayed as shown in FIG. And
The linked image file object "img / st
It requests the WWW server 131 to read in order to obtain “ar.gif”. In the above-described processing, the WWW server 131 already stores “im” in the “object storage table” 133a.
g / star.gif ", the external storage device 132
Read “img / star.gif” from the “object storage table” 133a without accessing
Reply to client 111.

Regarding other links, the WWW server 131 accesses the external storage device 132 in response to a request from the WWW client 111 because the WWW server 131 has already registered it in the “object storage table” 133a in the above-described processing. "Object storage table" 1 without
Read from 33a and reply. In addition, a link that does not exist on the WWW server 131 (http://www.xyz.co.jp/man1.htm
In the case of l), the WWW server 131 also executes step S2.
At 14, the WWW server 121 "www.xyz.co.j
When requesting the prefetching of the object to "p", the WWW server 121 registers the object in the "object storage table" 123a, so that the WWW server 121 responds to the request from the WWW client 111 by the external storage device 122.
Is read from the "object storage table" 123a and returned. Also, when there is an access request from the WWW client 112,
For the objects already registered in the “object storage table” 133a, the WWW server 131
Without accessing the external storage device 132, it reads and replies from the "object storage table" 133a.

Next, the processing executed by the object deletion unit 146 will be described with reference to the flowchart of FIG.

FIG. 6 is a flowchart showing a process executed by the object deleting unit according to the first embodiment of the present invention.

The object deleting unit 146 deletes objects that are no longer used or hardly used in the “object storage table” 133a.
Based on the “accumulation period”, a process of deleting from the “object accumulation table” 133a is performed. Further, the object deletion unit 146 performs step S301 described below.
To a step S303 are performed for all objects registered in the “object storage table” 133a.

First, in step S301, it is determined whether all objects have been processed. When all objects have been processed (step S301)
And the process ends. On the other hand, if all the objects have not been processed (NO in step S301), the process proceeds to step S302.

In step S302, it is determined whether the object to be processed has passed the accumulation period for determining deletion. If the accumulation period has not passed (step S30)
2 is NO), and the process ends. On the other hand, if the accumulation period has passed (YES in step S302), step S3
In step 03, the object to be processed is deleted from the “object storage table” 133a.

In the first embodiment, it is assumed that the “accumulation period” is already set in a predetermined procedure, for example, in a configuration file of the WWW server 131. In this case, when the date and time when the processing by the object deletion unit 146 is performed exceeds “last access date and time + accumulation period”, the object to be processed is deleted. For example, the HTML document “doc1.html” registered in the “object storage table” 133a is
Object deletion unit 146 after 2/20 13:00
Removed by

As described above, according to the first embodiment, the object requested to be accessed once by the WWW client 111 is stored in the internal storage device 1 from the second time.
Since it is stored in the “object storage table” 133a of 33, a quick response can be provided to the WWW client 111.

Further, with respect to other objects linked from the object, before the access request is issued from the WWW client 111, the internal storage device 133 is required.
Since it is stored in the “object storage table” 133a, a quick response can be provided to the WWW client 111. [Second Embodiment] In the first embodiment, a method is employed in which an object is stored in the "object storage table" 133a of the internal storage device 133 only when accessed by a WWW client. Therefore, in the first access, the object may be stored in the external storage device 132 in some cases.
, And a quick response to the WWW client 111 may not be possible.

Therefore, in the second embodiment, before an access request is received from the WWW client 111, it is stored in advance in the “object storage table” 133a of the internal storage device 133 of the WWW server 131 based on a pre-registration flag described later. Keep it. As a result, a quick response can be made to the WWW client 111.

Since the system configuration of the WWW server system according to the second embodiment is the same as that of the first embodiment,
Here, the description is omitted.

First, the configuration of the “object storage table” according to the second embodiment will be described with reference to FIG.

FIG. 7 is a diagram showing the structure of the “object storage table” according to the second embodiment of the present invention.

As shown in FIG. 7, in the “object storage table” used in the second embodiment, a “pre-registration flag” is provided as a new item in the “object storage table” 133a shown in the first embodiment. And
The object whose “pre-registration flag” has been registered as “YES” is set when the WWW server system starts.
Objects are stored in the “object storage table” from the external storage device 132. The setting of the “pre-registration flag” is performed by, for example, the WWW client 111.
This is performed from the input device 11 above.

Next, the processing executed in the second embodiment will be described with reference to FIG.

FIG. 8 is a flowchart showing the processing executed in the second embodiment of the present invention.

In the second embodiment, when the WWW server system starts, the object registration unit 147
Steps S601 to S604 described below
Are performed for all the objects registered in the “object storage table”. After that, the processing described in FIG. 5 is executed. Here, processing executed by the object registration unit 147 will be particularly described.

First, in step S601, it is determined whether all objects have been processed. When all objects have been processed (step S601)
YES), the process ends, and the process proceeds to the process described in FIG. On the other hand, if all the objects have not been processed (NO in step S601), step S602
Proceed to.

In step S602, it is determined whether or not the “prior registration flag” of the object to be processed stored in the “object storage table” is “YES”. If the “pre-registration flag” is not “YES” (NO in step S602), the process ends, and the process proceeds to the process described in FIG. On the other hand, if the "prior registration flag" is "YES" (YES in step S602), step S6
In step 03, an object to be processed is read from the external storage device 133. Then, in step S604, the object is registered in the “object storage table”.

In the example of FIG. 7, the HTML document “doc1.htm”
l ”and the HTML document“ doc2.html ”are targets of pre-registration, and indicate a state where the processing by the object registration unit 47 has been executed.

Thus, after the WWW server system is started, for example, when a request for the HTML document “doc1.html” is made from the WWW client 111, in the first embodiment, the access to the external storage device 132 occurs. However, in the second embodiment, since the object is already registered in the "object storage table", the requested object is read from the "object storage table" and returned without accessing the external storage device 132.

As described above, according to the second embodiment, a predetermined object is stored in the internal storage device 13 in advance.
3 is stored in the “object storage table”, so that a quick response can be provided even with the first access from the WWW client 111.

Even if the present invention is applied to a system including a plurality of devices (for example, a host computer, an interface device, a reader, a printer, etc.), a device including one device (for example, a copying machine, a facsimile machine) Etc.).

Further, an object of the present invention is to supply a storage medium storing a program code of software for realizing the functions of the above-described embodiments to a system or an apparatus, and to provide a computer (or CPU) of the system or apparatus.
And MPU) read and execute the program code stored in the storage medium.

In this case, the program code itself read from the storage medium realizes the functions of the above-described embodiment, and the storage medium storing the program code constitutes the present invention.

Examples of the storage medium for supplying the program code include a floppy disk, hard disk, optical disk, magneto-optical disk, CD-ROM, and CD.
-R, a magnetic tape, a nonvolatile memory card, a ROM, or the like can be used.

When the computer executes the readout program code, not only the functions of the above-described embodiment are realized, but also the OS (Operating System) running on the computer based on the instruction of the program code. ) May perform some or all of the actual processing, and the processing may realize the functions of the above-described embodiments.

Further, after the program code read from the storage medium is written into a memory provided on a function expansion board inserted into the computer or a function expansion unit connected to the computer, based on the instruction of the program code, It goes without saying that the CPU included in the function expansion board or the function expansion unit performs part or all of the actual processing, and the processing realizes the functions of the above-described embodiments.
