Definitions

  • the invention relates to a method for adapting the output format of a WVVW server according to the preamble of patent claim 1.
  • WWW servers are devices that provide data on the World Wide Web (WWW) that can be called up by service users. In addition to static files that do not change from browser to browser request, WWW servers also provide dynamically generated information. The information is provided in various formats such as HyperText Markup Language (HTML), Wireless Markup Language (WML) and Extensible HyperText Markup Language (XHTML). Since the Wireless Application Protocol (WAP) browser generally cannot process information in HTML format and the World Wide Web (WWW) browser cannot process information in WML format, the WWW server must respond to a browser request with the respond to the information format appropriate for the browser. The simplest solution to this problem is that the user or browser requests exactly the format that can be processed using the so-called Uniform Resource Locator (URL) or address.
  • URL Uniform Resource Locator
  • the object of the invention is to provide a method which provides a service user with information requested by a WWW server in an output format which can be processed by the browser used.
  • the invention is based on the fact that in addition to their browser identity in a HyperText Transfer Protocol (HTTP) request to a WWW server, browsers usually also send additional information: the so-called "Accept HTTP Header Field". In this header field, the browser informs the server which formats the browser can process. This additional information consists of a certain character string. With a few exceptions, for example, WAP browsers send the string "text / vnd.wap.wml" in this Accept HTTP Header Field. HTTP browsers should send the string "text / html" in the Accept HTTP Header Field to tell the WWW server that they can display HTML. However, this is usually not the case with standard HTTP browsers.
  • HTTP HyperText Transfer Protocol
  • the “User-Agent HTTP Header Field” can be evaluated, whereby it can be determined whether the browser is known to the server or the intermediary.
  • FIG. 1 shows a possible flowchart of the method steps that are carried out according to the invention when the browser requests an information from a WWW server by the WWW server or a mediating device.
  • Step 0 There is a request for information from a browser to a WWW server.
  • Step 1 Differentiate between WAP and non-WAP browsers using
  • Step 2 If the character string "text / vnd.wap.wml" is present, the requesting browser is a WAP browser: Step 3: Verification of browser identity using "user-agent
  • Step 5 The WWW server sends the requested
  • Step 7 The WWW server sends the requested
  • Step 8 If string "text / vnd.wap.wml" is not available:
  • Step 9 Check the browser identity using "user-agent HTTP header fields". It is determined whether this browser is known to the WWW server as a WAP browser and for which a suitable presentation design is available. Step 10: If the browser is a WAP browser:
  • Step 11 The WWW server sends the requested
  • Step 12 If the browser is not a WAP browser:
  • Step 13 Checking the browser identity, whether there is a suitable presentation design for this browser.
  • Step 14 If the browser is known:
  • Step 15 The WWW server sends the requested information to the browser in the appropriate format (HTML) and presentation design.
  • Step 16 If the browser is unknown: Step 17: The WWW server sends the requested information to the browser in the appropriate format (HTML).
  • HTML HyperText Markup Language
  • Step 12 can e.g. to the extent that it can also be recognized whether a browser can process XHTML.
  • the "Accept HTTP Header Field" is examined for the presence of the character string "application / xhtml + xml". If this character string is present, the browser can process XHTML.

Abstract

L'invention concerne un procédé permettant d'ajuster le format de sortie d'un serveur Web à un format adapté à un navigateur Web. Selon ce procédé, en cas de demande d'information du navigateur auprès du serveur Web, certains champs de données du protocole HTTP sont analysés par le serveur Web ou par un dispositif intermédiaire et, à l'aide du résultat de l'analyse, les informations demandées sont envoyées au navigateur dans un format et/ou un type de présentation adaptés au navigateur.
