Abstract

Systems and methods which provide an extensible caching framework are disclosed. These systems and methods may provide a caching framework which can evaluate individual parameters of a request for a particular piece of content. Modules capable of evaluating individual parameters of an incoming request may be added and removed from this framework. When a request for content is received, parameters of the request can be evaluated by the framework and a cache searched for responsive content based upon this evaluation. If responsive content is not found in the cache, responsive content can be generated and stored in the cache along with associated metadata and a signature formed by the caching framework. This signature may aid in locating this content when a request for similar content is next received.

Claims

1. A method for caching, comprising:

configuring an extensible caching framework on a web server to allow for a plurality of modules to be added to and removed from the extensible caching framework;

receiving, at the web server, an incoming request for content from a browser application running on a client computer connected to the web server over a network;

evaluating the incoming request for content, wherein the extensible caching framework on the web server performs the evaluating utilizing at least one of the plurality of modules, wherein the at least one of the plurality of modules invoked for the evaluating returns data to the extensible caching framework on the web server, and wherein the data includes a status which indicates whether the incoming request for content is to be;

mapped to a cache file stored in a cache accessible by the extensible caching framework;

or

passed onto an application server connected to the web server for dynamic evaluation and content generation; and

returning content responsive to the incoming request for content to the client computer over the network, wherein the content responsive to the incoming request for content is either served from the cache accessible by the extensible caching framework on the web server or is dynamically generated by the application server connected to the web server, depending upon the status returned by the at least one of the plurality of modules invoked for the evaluating,

wherein all of the plurality of modules request that content be served from the cache if possible, further comprising;

generating a string or signature to be used for a first cache file name, wherein the extensible caching framework on the web server performs the generating by accumulating or concatenating strings returned from each of the plurality of modules and hashing the accumulated or concatenated strings.

2. The method according to claim 1, further comprising:

storing the content dynamically generated by the application server in the cache using the first cache file name generated by the extensible caching framework on the web server.

3. The method according to claim 2, further comprising:

receiving a second request for content at the web server;

generating a second cache file name, wherein the second cache file name is identical to the first cache file name, and wherein the extensible caching framework on the web server performs the generating; and

serving the content responsive to the second request from the cache utilizing the second cache file name.

4. The method according to claim 1, wherein each of the plurality of modules is responsible for a different parameter associated with the incoming request.

5. The method according to claim 1, wherein a first module of the plurality of modules is capable of evaluating capabilities of the browser application running on the client computer.

6. The method according to claim 5, wherein the first module is operable to:

locate a template associated with the incoming request for content; and

determine whether or not the template is sensitive to browser features of the browser application running on the client computer.

7. A computer program product comprising at least one non-transitory computer readable medium storing instructions translatable by at least one processor to perform:

receiving, at a web server, an incoming request for content from a browser application running on a client computer connected to the web server over a network;

evaluating the incoming request for content, wherein an extensible caching framework on the web server performs the evaluating utilizing one or more of a plurality of modules registered with the extensible caching framework, wherein the at least one of the plurality of modules invoked for the evaluating returns data to the extensible caching framework on the web server, and wherein the data includes a status which indicates whether the incoming request for content is to be;

mapped to a cache file stored in a cache accessible by the extensible caching framework;

or

passed onto an application server connected to the web server for dynamic evaluation and content generation; and

returning content responsive to the incoming request for content to the client computer over the network, wherein the content responsive to the incoming request for content is either served from the cache accessible by the extensible caching framework on the web server or is dynamically generated by the application server connected to the web server, depending upon the status returned by the at least one of the plurality of modules invoked for the evaluating,

wherein all of the plurality of modules request that content be served from the cache if possible and wherein the instructions are further translatable by the at least one processor to perform;

accumulating or concatenating strings returned from each of the plurality of modules and hashing the accumulated or concatenated strings to generate a string or signature to be used for a first cache file name.

8. The computer program product of claim 7, wherein the instructions are further translatable by the at least one processor to perform:

storing the content dynamically generated by the application server in the cache using the first cache file name.

9. The computer program product of claim 8, wherein the instructions are further translatable by the at least one processor to perform:

receiving a second request for content at the web server;

generating a second cache file name, wherein the second cache file name is identical to the first cache file name; and

serving the content responsive to the second request from the cache utilizing the second cache file name.

10. The computer program product of claim 7, wherein each of the plurality of modules is responsible for a different parameter associated with the incoming request.

11. The computer program product of claim 7, wherein a first module of the plurality of modules is capable of evaluating capabilities of the browser application running on the client computer.

12. The computer program product of claim 11, wherein the first module is operable to:

locate a template associated with the incoming request for content; and

determine whether or not the template is sensitive to browser features of the browser application running on the client computer.

13. A system, comprising:

a web server;

an extensible caching framework implemented on the web server;

a plurality of modules registered with the extensible caching framework;
