Receives HTML as content from the Web server 1 and analyzes the HTML by the HTML analysis unit 3-6 to generate the content to be transmitted to the information terminal 2; Instead, it is regenerated by the generation grammar in the gateway server 3.

In the first place, the HTML grammar itself has various degrees of freedom such as "tag notation may be in uppercase and lowercase" and "tag attribute may have double quotes". The terminal 2 normally describes the grammar of the HTML analysis unit so as to allow these degrees of freedom. Therefore, when regenerating the HTML to be transmitted to the information terminal 2 from the HTML received and analyzed by the gateway server 3 from the Web server 1, the HTML is generated so as to absorb the degree of freedom. That is, the content conversion unit 3-3 of the gateway server 3 is changed to the HTML analysis unit 3-6.
When converting the content from the analysis result of HTML, HTML according to the rules such as “generate tags in all uppercase” and “generate tag attributes with double quotes”
Is generated and stored in the content information storage unit 3-4.

As a result, the degree of freedom of the HTML language can be absorbed by the gateway server 3, so that the information terminal 2
Now, we are aware of the degree of freedom of the HTML language in advance,
There is no need to construct the processing logic of the analysis unit (the grammar of the HTML analysis unit may be constructed in accordance with the grammar of the gateway server 3), and the HTML analysis processing logic can be simplified.

If so, a series of processes from generation of a content acquisition request to the Web server 1 to content conversion processing is skipped, and information stored in the content information conversion unit 3-4 exists from the information terminal 2 which is not the same type If it is a request, a series of processing from generation of a content acquisition request to the Web server 1 to HTML analysis processing is skipped. Thereby, the gateway server 3
The data before and after the conversion is stored, and in response to a request to obtain the stored content data, a data acquisition request is not issued to the Web server 1, so that communication traffic can be suppressed. , The data conversion time can be reduced.

(Embodiment 19) In the nineteenth embodiment, in the first embodiment, together with a content acquisition request from the information terminal 2, an HTTP extension header indicating a conversion request flag in the following format is transmitted to the gateway server. 3 and the gateway server 3 performs conversion according to the transmitted HTTP extension header.

For this realization, when the HTTP analysis / generation unit 2-4 of the information terminal 2 generates a content acquisition request, it generates a conversion request flag having a header body consisting of a series of "0 or 1". I do. Here, one character in the header body means the following conversion request. -First character: Convert frame-Second character: Convert table-Third character: Convert style sheet-Fourth character: Convert font and layout information For example, if the field name of the extension header is "X-Trans"
-Flag ”as the extension header“ X-Trans-F
lag: 0110 "means that tables and stylesheets are converted and the others are not.

Then, the gateway server 3 receives the content acquisition request from the information terminal 2 via the communication unit 3-1 and analyzes the content acquisition request. The content acquisition request is “X-Trans-Flag: 011
A conversion request flag such as "0" is included as an extension header, and the HTTP analysis / generation unit 3-5 extracts this flag information and stores it in the client information storage unit 3-2. Then, through a series of processing from content acquisition to the Web server 1 to HTML analysis processing, the content conversion unit 3-2
Performs the content conversion. At this time, the content is converted according to the conversion request flag stored in the client information storage unit 3-2. That is, according to the present embodiment, only the table and the style sheet are converted.

As a result, it is possible to prevent the gateway server 3 from unconditionally converting the content, and the information terminal 2
Since the control of the content conversion can be performed at the time of changing the function of the information terminal 2, it is only necessary to change the setting of the conversion flag, and there is no need to change the processing procedure of the gateway server 3. The effect on the server 3 can be minimized.
