Abstract

A method and system are disclosed for cache management and regeneration of dynamically-generated locale-sensitive content (DGLSC) in one or more server computers within a client-server computer network. One embodiment of the method of this invention can comprise receiving a request for content from a user at a client computer and determining the user'"'"'s locale preference with, for example, an automatic locale detection algorithm. The requested content can be dynamically generated from a template as DGLSC based on the user locale preference. If the template is a cacheable template, a locale-sensitive filename can be generated for the DGLSC based on the user locale preference. The locale-sensitive filename can be associated with the DGLSC. The DGLSC can be cached in a locale-sensitive directory, such that it can be served (and thus avoid duplicative generation of the same content) in response to subsequent requests from users having the same locale preference The DGLSC is then served to the requesting user at his or her client computer.

Claims

1. A method for cache management and regeneration of dynamically-generated locale-sensitive content (“

DGLSC”

) in one or more server computers within a client-server computer network, comprising the steps of;

receiving a first request for a web page from a first user at a client computer via a web browser;

determining said first user'"'"'s locale preference with an automatic locale detection algorithm, wherein a locale corresponds to at least a geographic region;

dynamically generating a first set of content for the requested web page from a template as a first DGLSC based on said first user'"'"'s locale preference;

receiving a second request for the web page from a second user having a second user'"'"'s locale preference;

dynamically generating a second set of content for the requested web page from the template as a second DGLSC based on the second user'"'"'s locale preference instead of the first DGLSC;

if said template is marked as cacheable to indicate that content generated from said template should be cached;

generating a first locale-sensitive filename for said first DGLSC based on said first user'"'"'s locale preference and associating said first DGLSC with said first locale-sensitive filename;

generating a second locale-sensitive filename for said second DGLSC based on said second user'"'"'s locale preference and associating said second DGLSC with said second locale sensitive filename;

caching said first DGLSC in at least one server computer in a locale-sensitive directory to be served in response to subsequent requests having the same locale preference as the first user'"'"'s locale preference and caching the second DGLSC in the locale-sensitive directory to be served in response to subsequent requests having the same locale preference as the second user'"'"'s locale preference; and

serving said first DGLSC to said first user at said client computer; and

serving said second DGLSC to said second user.

2. The method of claim 1, wherein said first locale-sensitive filename comprises coded information associated with said first user'"'"'s locale preference.
