Dynamic web page construction based on determination of client device location

A computer program product stored in a computer-readable storage medium and executable by a data processing system for serving a customized web page, the computer program product comprising instructions for performing steps of:

• receiving, by a server data processing system, a user-initiated request for a specific web page from a first client browser, the request including (i) a geographic location data string identifying a first location of the first client browser and (ii) an identifier for the specific web page;
• generating, by the server data processing system responsive to the request, the customized web page using (i) the geographic location data string to select a given one of a set of location-specific page elements having content including a physical location in proximity to the first location of the first client browser and (ii) the specific web page, wherein elements from both the specific web page and the given one of the set of location-specific page elements are included in the customized web page;
• receiving, by the server data processing system, a subsequent request for the web page from either the first client browser or a second client browser different from the first client browser;
• determining, by the server data processing system, if the subsequent request originates from a second location that is proximate to the first location of the first client browser;
• and
• providing, by the server data processing system, a cached version of the customized web page if the second location is proximate to the first location.

A web server, comprising:

• a processor and memory;
• first instructions to receive a user-initiated request for a specific web page from a first client browser, the request including (i) a geographic location data string identifying a first location of the first client browser and (ii) an identifier for the specific web page;
• second instructions, responsive to the first instructions, to generate a customized web page using (i) the geographic location data string to select a given one of a set of location-specific page elements having content including a physical location in proximity to the first location of the first client browser and (ii) the specific web page, wherein elements from both the specific web page and the given one of the set of location-specific page elements are included in the customized web page;
• third instructions to receive a subsequent request for the web page from either the first client browser or a second client browser different from the first client browser;
• fourth instructions to determine if the subsequent request originates from a second location that is proximate to the first location of the first client browser;
• and
• fifth instructions to provide a cached version of the customized web page if the second location is proximate to the first location.

A method for generating and serving a customized web page by a server data processing system, comprising steps implemented by the server data processing system of:

• receiving a user-initiated first request for a specific web page from a client browser, the first request being associated with a geographic location data string identifying a location of the client browser;
• responsive to the first request being received, dynamically generating the customized web page using (i) the geographic location data string to select a given location-specific page element and (ii) the specific web page, wherein elements from both the specific web page and the given one of the set of location-specific page elements are included in the customized web page;
• caching the customized web page for future use;
• serving the customized web page in response to the first request;
• responsive to receipt of a second request for the web page, determining whether the second request originates within a given distance from the location;
• and
• if so, retrieving and serving the cached customized web page in response to the second request.
