Abstract

A method to preview new cacheable content may include adding a skip-cache element to a request to preview the new cacheable content before replacing any existing content in a cache or caching the new content. The method may also include bypassing cache processing for the request in response to the request including the skip-cache element and the skip-cache element being defined in a cache policy.

Claims

1. A method to preview new cacheable content, comprising:

adding a skip-cache element to a request to preview the new cacheable content before replacing any existing content in a cache or caching the new content; and

bypassing cache processing for the request in response to the request including the skip-cache element and the skip-cache element being defined in a cache policy.

2. The method of claim 1, further comprising defining the skip-cache element as a property in the cache policy.

3. The method of claim 1, further comprising preventing any component of a response to the request from being saved.

4. The method of claim 1, further comprising preventing any component of a response to the request from being retrieved from the cache.

5. The method of claim 1, further comprising performing normal cache processing in response to a non-preview request.

6. The method of claim 1, further comprising allowing any existing cache content using a same cache policy as the new cacheable content to be processed by the cache until the new cacheable content has been previewed and permitted to replace any existing cache content.

7. The method of claim 1, further comprising preventing any data integrity issues associated with invalidating the new cacheable content by not storing the new cacheable content in the cache until the new cacheable content has been previewed and permitted to replace any existing cache content.

8. The method of claim 1, further comprising replacing the existing cache content with the new cacheable content in response to previewing and validating the new cacheable content.

9. The method of claim 1, further comprising performing a non-cached execution of the request in response to the request including the skip-cache element and a same skip-cache element being defined in the cache policy.

10. A system to preview new cacheable content, comprising:

a server;

a cache associated with the server; and

a module to add a skip-cache element to a request to preview the new cacheable content before replacing any existing content in the cache or caching the new cacheable content.

11. The system of claim 10, further comprising a cache policy including a definition of the skip-cache element.

12. The system of claim 11, further comprising a cache handler adapted to check for presence of the skip-cache element in the request and to bypass cache processing for the request in response to the request including the skip-cache element and the skip-cache element being defined in the cache policy.

13. The system of claim 10, wherein the module to add the skip-cache element comprises a servlet filter.

14. The system of claim 10, wherein the new cacheable content shares a same cache policy with the existing content to be replaced by the new cacheable content.

15. A computer program product to preview new cacheable content, the computer program product comprising:

a computer usable medium having computer usable program code embodied therein, the computer usable medium comprising;

computer usable program code configured to add a skip-cache element to a request to preview the new cacheable content before replacing any existing content in a cache or caching the new content; and

computer usable program code configured to bypass cache processing for the request in response to the request including the skip-cache element and the skip-cache element being defined in a cache policy.

16. The computer program product of claim 15, wherein the computer usable medium further comprises:

computer usable program code configured to preventing any component of a response to the request from being saved; and

computer usable program code configured to prevent any component of the response to the request from being retrieved from the cache.

17. The computer program product of claim 15, wherein the computer usable medium further comprises computer usable program code configured to perform normal cache processing in response to a non-preview request.

18. The computer program product of claim 15, wherein the computer usable medium further comprises computer usable program code configured to allow any existing cache content using a same cache policy as the new cacheable content to be processed by the cache until the new cacheable content has been previewed and permitted to replace any existing cache content.

19. The computer program product of claim 16, wherein the computer usable medium further comprises computer usable program code configured to prevent the new cacheable content from being cached until the new cacheable content has been previewed and permitted to replace any existing cache content.

20. The computer program product of claim 16, wherein the computer usable medium further comprises computer usable program code configured to perform a non-cached execution of the request in response to the request including the skip-cache element and a same skip-cache element being defined in the cache policy.
