Abstract

Described herein is a hyperlink browsing system that includes a plurality of mobile hyperlink browsers that communicate wirelessly with a plurality of servers having geographically-dependent information content. The hyperlink browsers have access to positioning receivers that generate varying geographical coordinates indicating the varying locations of the hyperlink browsers. When submitting HTTP requests, the hyperlink browsers include the geographical coordinates. The servers recognize the parameters and customize returned content in accordance with the geographic locations of the requesting users.

obtaining the geographical coordinates of the mobile client from a global positioning receiver associated with the mobile client.

4. A computer-readable storage medium having stored thereon a hyperlink browser program, the hyperlink browser program being executable by a mobile computer to perform steps comprising:

accepting a designation of hyperlinked content from a user;

obtaining current geographical coordinates of the mobile computer from a global positioning receiver associated with the mobile computer;

in response to user designation of hyperlinked content, sending an HTTP request to a hyperlinked content network over a wireless transmission medium; and

including the current geographical coordinates of the mobile computer in the HTTP request.

5. A computer-readable storage medium as recited in claim 4, wherein the geographical coordinates are included in an HTTP request header along in the HTTP request.

6. A computer-readable storage medium as recited in claim 4, the steps further comprising:

receiving and rendering geographically-dependent content from the hyperlinked content network as a result of the HTTP request.

7. A computer-readable storage medium as recited in claim 4, the steps further comprising:

receiving geographically-dependent content from the hyperlinked content network as a result of the HTTP request, wherein a valid zone specification is returned to the hyperlink browser program in conjunction with the geographically-dependent content, the valid zone specification indicating a geographical zone within which the geographically-dependent content is considered valid.

8. A computer-readable storage medium as recited in claim 4, the steps further comprising:

receiving geographically-dependent content from the hyperlinked content network as a result of the HTTP request, wherein a valid zone specification is returned to the hyperlink browser program in conjunction with the geographically-dependent content, the valid zone specification indicating a geographical zone within which the geographically-dependent content is considered valid; and

sending a new HTTP request when the mobile computer leaves the indicated geographical zone.

9. A computer-readable storage medium as recited in claim 4, the steps further comprising:

receiving geographically-dependent content from the hyperlinked content network as a result of the HTTP request, wherein a valid radius is returned to the hyperlink browser program in conjunction with the geographically-dependent content, the valid radius indicating a radius from the current geographical coordinates within which the geographically-dependent content is considered valid; and

invalidating the geographically-dependent content when the mobile computer leaves an area encompassed by the radius.

10. A mobile information system comprising:

a mobile client running a mobile hyperlink browser to communicate with one or more remote servers, wherein geographically-dependent hyperlinked content is available from the servers;

wherein the mobile hyperlink browser sends resource requests to the servers; and

wherein a resource request from the mobile hyperlink browser includes geographical coordinates indicating a current location of the mobile hyperlink browser.

11. A mobile information system as recited in claim 10, wherein the servers return geographically-dependent content having a valid zone specification indicating a geographical zone within which the geographically-dependent content is considered valid;

and

the mobile hyperlink browser invalidates geographically-dependent content when the mobile client leaves the geographical zone specified by the valid zone specification.

12. A mobile information system as recited in claim 10, wherein the servers return valid zone specifications in conjunction with returned geographically-dependent content, the valid zone specifications indicating geographical zones within which the returned geographically-dependent content is considered valid;

and

the mobile hyperlink browser sends a new resource request when the mobile hyperlink browser leaves the geographical zone specified for particular returned geographically-dependent content.

13. A mobile information system comprising:

a computer;

a wireless communications interface that provides communications between the computer and a remote server over a wireless communications medium;

a hyperlink browser that executes on the computer, the hyperlink browser sending resource requests to the remote server over the wireless communications medium;
