- HDD Hard Disk Drive
- HTTP client that uses these HTTP servers is executed by a client computer.
- HTTP clients There are two types of HTTP clients, one that communicates with the HTTP server in domain (1) and one that communicates with the HTTP server in domain (2). Described in the description. All data and programs handled by the HTTP client are input to and output from the storage means such as the HDD of the client computer.
- Internet Explorer of Microsoft Corporation is used as an HTTP client in the OS environment of Windows (registered trademark) of the company!
- the user of the client computer operates the input device and requests the HTTP client to read the content program.
- the HTTP client requests the domain (1) HTTP server to provide a content program.
- the HTTP server in domain (1) reads out the requested content program and provides it to the requesting HTTP client.
- the content program is HTML that provides various information to the user of the client computer.
- This HTML includes Javascript (registered trademark) logic, which is hereinafter referred to as a data request program (first program).
- the HTTP client of the domain (1) that has received the content program executes the content program (main program) including the data request program.
- the content program provides predetermined information to the user of the client computer via an output device such as a display device. Also, the content program operates the data request program when it enters the execution stage of the data request program. Here, it is assumed that a predetermined callback function is implemented in the data request program.
- the execution of the data request program may be performed, for example, when the user instructs the execution of the data request program from the input device.
- the data request program operates so that the content program in the domain (1) uses data provided from the HTTP Sano in the domain (2).
- the data request program First, an HTTP client that communicates with the domain (2) is started, and this HTTP client is made to obtain a data acquisition program and a data distribution program from the HTTP server of the domain (2).
- the data acquisition program and the data distribution program are included in HTML as Javascript (registered trademark) logic!
- Requests to this domain (2) HTTP server are made by the GET method in this embodiment.
- the data request program When instructing this GET method to the HTTP client of the domain (2), the data request program outputs the identifier id of the data request program so that the data distribution program can obtain the id of the data request program.
- a Javascript (registered trademark) program information on the URI (Uniform Resource Identifier) displayed in the browse area where the program is executed can be acquired by referring to the property of the location object.
- the GET method is instructed to the HTTP client of domain (2), if the identifier id of the data request program is passed as an argument, the data distribution program executed by the HTTP client of domain (2) will be It is possible to obtain the identifier id.
- the identifier id is, for example, a data request It can be something like a program function name or a callback function name.
- the data request program that has completed the processing so far enters a state where the callback function waits for processing. Meanwhile, the content program can continue other processes.
- the HTTP server of domain (2) receives a request from the HTTP client of domain (2), prepares a data acquisition program and a data distribution program, and provides them to the HTTP client of domain (2).
- the data distribution program is passed the id of the data request program.
- the data acquisition program and the HTTP client receiving this provision first execute the data acquisition program (second program).
- the data acquisition program acquires the data that the content program of domain (1) wants to use from the HTTP server of domain (2).
- the data acquisition program requests the HTTP server of the domain (2) to acquire predetermined data using an event from the input device as a trigger.
- the HTTP server of domain (2) prepares the requested data and obtains the data acquisition program.
- the data acquisition program stores the data acquired from the HTTP server of domain (2) in the storage means.
- the HTTP client in the domain (2) executes a data distribution program (second program).
- the data distribution program determines whether the data stored in the storage means by the data acquisition program is long enough to be exchanged with the GET method, and if it exceeds the length that can be exchanged with the GET method, it is exchanged with the GET method. Divide the data into possible lengths, and add serial number p to each divided data piece V. In addition, the number num of data pieces divided into the first data piece is added. Then, the data distribution program stores the association between these data pieces and additional information in the storage means.
- the data distribution program activates an HTTP client that communicates with the HTTP server in the domain (1), and generates the program execution area managed by the HTTP client by the number of data pieces divided earlier.
- the program execution areas (1) to (3) are illustrated on the assumption that the number of data divisions is three.
- this program execution area is a frame generated by an iframe tag.
- the data distribution program reads each piece of data divided previously from the storage means and distributes each piece of data individually to each of the program execution areas (1) to (3). At this time, the GET method is used.
- the data distribution program gives a GET statement to each of the program execution areas (1) to (3).
- Each piece of data is attached to each GET statement as an argument of the GET statement.
- the additional information associated with each data piece and the id of the data requesting program is attached to each GET statement as an I number.

- the association between the serial number p of the data piece and the data piece V is passed through the bow I (in this embodiment, the value of nu m is provided only from the transfer program (1)).
- the transfer of data to each transfer program power data request program This can be done simultaneously with the process of calling the data request program.
- the callback function of the data request program in the content program is a function named “cbfonc”. Since this function is implemented in the parent of the parent in terms of the transfer program power, by executing self.parent.parent.cbfonc (argl, ar g2, ...) in the transfer program logic , Arguments argl, arg2, ... are passed to the data request program.
- the data request program Upon receipt of this value, the data request program restarts the process. First, the data request program determines whether it has received the number of data pieces V corresponding to the number of data divisions num, and if all of the divided data pieces are ready. Then, the data pieces V are connected in the order of the serial number p of the data pieces, thereby reconstructing the data provided from the HTTP server in the domain (2).

- a content producer can use data such as an authentication service of another domain by simply preparing a script language description necessary on the producer side. For this reason, for example, an EC site with excellent security can be easily constructed, and data from another domain can be used without newly creating a server side. Also, even if the length and data cannot be passed with the GET method, the data piece is connected to the HTTP client that executes the content program using the GET method by dividing it into data pieces, and the data is reproduced. You can pass data using the GET method even for long data. The
- the present invention is not limited to the above embodiment.
- the program execution area that the data distribution program opens in the domain (1) is not limited to the frame using the iframe tag, and an individual window object may be opened for each program execution area.
- the embodiment has been described in which the value of the data division number num is associated with only the first data piece, it is possible to associate the data division number num with all data pieces. Without associating these, it is possible to create one more program execution area that passes only the value of the data division number num and pass the value.
- Another method for passing data to the program execution area of the data distribution program domain (1) is to use the POST method without using the GET method.
- a CGI corresponding to POST is prepared in advance on the HTTP server of domain (1), and the data distribution program passes the data to the HTTP server of domain (1) via POST, and the data is sent on the CGI side.
- the HTTP client that starts the data request program can be operated without being displayed, or it may be displayed as required.
- the HTTP client that starts the data request program and the HTTP client that starts the data distribution program does not matter whether the startup method is a new window or a frame.

In such a case, the process does not wait until the entire information piece is received. When the name and domain information pieces are received, other variables are ignored and only the information of name and domain information is reconstructed. It may be possible to decide on the data request program side so that it can be used.
- the data division program may set an information piece identifier for each information piece in order to identify each divided piece of information.
- the “serial number” in the above embodiment corresponds to this information piece identifier.
- the information fragment identifier may be given by, for example, a sequence number such as 1, 2, 3, ... for the order of the divided information fragments, or if the information fragments are separated for each parameter as described above, name
- the variable name of each parameter such as, date etc. may be used as an information piece identifier.
- the data division program may give an identifier of original information to each piece of information. This is to make it possible for the data requesting program side to select information pieces necessary for reconstructing the original information based on the identifier of the original information.
- the identifier of the original information the same identifier may be given for each piece of information, or a different identifier may be given to the piece of information.
- a method for associating the different identifiers with common source information is registered on the data request program side, and the data request program power is referred to the method for associating with the source information. It is conceivable to select information pieces that share the same.
