Abstract

The present invention is based on a concept to provide session and profile management for network communication, especially over hypertext transfer protocol (HTTP), employing available communication methods. Session and profile management is available and standardized for mobile communication by the means of the wireless session protocol (WSP) employable for wireless application protocol (WAP) communication. This wireless session protocol (WSP) is limited to mobile communication. The analog communication standard hypertext transfer protocol (HTTP) available and standardized for wireline communication does not offer a session and profile management. The present invention offers a method to establish an analog session and profile management by the means of cookies or modified uniform resource locators (URL) even over the hypertext transfer protocol (HTTP) without requiring substantial changes to the hypertext transfer protocol (HTTP) standard.

retrieving (S5.52) said profile data,

generating (S5.53) a response in accordance with said request, wherein said response is based on said profile data and includes a plurality of uniform resource locators (URLs),

processing (S5.54) said uniform resource locators (URLs) by including therein information for retrieving profile data, and

transmitting (S5.55) said response to said requesting device (100).

19. Method according to claim 2, wherein said profile data are available for being retrieved for a certain period of time.

20. Method according to claim 19, wherein said period of time starts with the initial receiving of said profile data.

21. Method according to claim 20, wherein said period of time is terminated with the removal of said profile data.

22. Method according to claim 2, wherein said step of generating a response further comprises the steps of:

generating (S1.27, S1.16, S5.28, S5.57) a server request based on the client request,

transmitting (S1.28, S1.17, S5.29, S5.58) said server request,

receiving (S1.29, S1.18, S5.30, S5.59) a server response in accordance with said server request and
