Abstract

A method, a system, an apparatus, and a computer program product are presented for a fragment caching methodology. After a message is received at a computing device, a fragment in the message body is cached. Cache ID rules from an origin server accompany a fragment to describe a method for forming a unique cache ID for the fragment such that dynamic content can be cached away from an origin server. A cache ID may be based on a URI and/or query parameters and/or cookies that are associated with a fragment. After user authentication, a cookie containing the user'"'"'s role may be used in subsequent requests for role-specific fragments and in the cache identifier for role-specific fragments, thereby allowing requests from other users for role-specific fragments to be resolved in the cache when the users have the same role because these users would also have the same cookie.

Claims

1. A method for processing objects within a data processing system in a network, the method comprising:

storing a content object in a cache at a first computing device using a cache identifier for the content object that is based on a URI (Uniform Resource Identifier) for the content object and a cookie value associated with the content object;

receiving a request containing the URI and an associated cookie having the cookie value at the first computing device;

retrieving the content object from the cache at the first computing device using the URI and the cookie value; and

returning from the first computing device a response containing the content object.

2. The method of claim 1 wherein the cookie value is associated with a user role.

3. The method of claim 2 wherein the content object is a role-specific fragment.

4. A computing device apparatus for processing objects within a data processing system in a network, the computing device apparatus comprising a processor, a data bus coupled to the processor, and a memory coupled to the processor through the data bus for storing computer readable code to be processed by the processor for:

storing a content object in a cache using a cache identifier for the content object that is based on a URI (Uniform Resource Identifier) for the content object and a cookie value associated with the content object;

receiving a request containing the URI and an associated cookie having the cookie value;

retrieving the content object from the cache using the URI and the cookie value; and

returning a response containing the content object.

5. The computing device apparatus of claim 4 wherein the cookie value is associated with a user role.

6. The computing device apparatus of claim 5 wherein the content object is a role-specific fragment.

7. A computer program product in a non-transitory computer readable storage medium for use within a data processing system in a network for processing objects, the computer program product comprising:

instructions for storing a content object in a cache using a cache identifier for the content object that is based on a URI (Uniform Resource Identifier) for the content object and a cookie value associated with the content object;

instructions for receiving a request containing the URI and an associated cookie having the cookie value;

instructions for retrieving the content object from the cache using the URI and the cookie value; and

instructions for returning a response containing the content object.

8. The computer program product of claim 7 wherein the cookie value is associated with a user role.

9. The computer program product of claim 8 wherein the content object is a role-specific fragment.
