Abstract

A web page is generated by locating an area in a website to place the page and selecting a template for the page. An output cache manager allows a user to attach a cache profile in the form of metadata to the template and the area in the website. The output cache manager uses the metadata to identify the cache profile that is associated with the web page when the page is rendered. The cache profile identifies the page output directive caching parameters that are associated with a web page when the page is rendered. A cache profile may be inherited by web pages that are dependent on the site in which the page resides such that a previously established cache profile is overridden. The cache profile may be created and modified by any authorized user. Any modification to the cache profile may be applied to all web pages that are associated with the cache profile.

Claims

1. A computer-implemented method for managing an output cache, comprising:

receiving a request for a web page associated with a website;

determining a cache profile, wherein the cache profile is separately stored from a web page template of a web page and linked to the web page template via metadata of the cache profile, wherein the cache profile is determined based on the web page hierarchical level location within a website hierarchy of the website, wherein cache parameters of the cache profile and the link between the cache profile and the web page template are modifiable without accessing the web page template;

determining whether the web page is stored in the output cache based on the cache profile;

determining whether the web page is valid when the web page is stored in the output cache;

returning the web page from the output cache when the web page is stored in the output cache and the web page is valid;

rendering the web page from a server when the web page is not stored in the output cache; and

rendering the web page from the server when the web page is not valid.

2. The computer-implemented method of claim 1, wherein determining whether the web page is stored in the output cache further comprises matching the cache parameters of the cache profile associated with the requested web page to caching parameters identified in a cache key stored in the output cache.

3. The computer-implemented method of claim 1, further comprising:

generating a cache key for the rendered web page, wherein the cache key identifies caching parameters for the rendered web page; and

storing the rendered web page and the cache key in the output cache.

4. The computer-implemented method of claim 1, wherein determining whether the web page is valid comprises determining whether the web page was modified after the web page was stored in the output cache.

5. The computer-implemented method of claim 1, wherein determining whether the web page is valid comprises determining whether the web page was stored in the output cache longer than a predetermined time duration.

6. The computer-implemented method of claim 1, further comprising clearing the web page from the output cache when the web page is not valid.

7. The computer-implemented method of claim 1, wherein the caching parameters include an access control list that associates members of the access control list with parameters.

8. The computer-implemented method of claim 1, further comprising automatically associating the cache profile with another web page having a same website hierarchical level as the website hierarchical level of the requested web page.

9. The computer-implemented method of claim 1, further comprising disabling output caching for a website that includes the web page.

10. The computer-implemented method of claim 1, further comprising overriding the cache profile by a cache profile associated with a web page having a higher website hierarchical level as the requested web page.

11. The computer-implemented method of claim 1, further comprising modifying the cache profile, applying the modified cache profile to the web page template of the requested web page, and automatically applying the modified cache profile to other web pages of the website having a same website hierarchical level as the website hierarchical level of the requested web page.

12. A system for managing an output cache, comprising:

a client comprising a browser and the output cache, wherein a request for a web page associated with a website is received at the browser;

a server coupled to the client, wherein;

the server is arranged to determine a cache profile, wherein the cache profile is separately stored from a web page template of a web page and linked to the web page template via metadata of the cache profile, wherein the cache profile is determined based on the web page hierarchical level location within a website hierarchy of the website, wherein cache parameters of the cache profile and the link between the cache profile and the web page template are modifiable without accessing the web page template, and

an output cache manager coupled to the server and the client, wherein the output cache manager is arranged to;

locate the template and the cache profile,

determine whether the web page is stored in the output cache based on the cache profile,

determine whether the web page is valid when the web page is stored in the output cache, and

return the web page to the browser from the output cache when the web page is stored in the output cache and the web page is valid.

13. The system of claim 12, wherein the server is further arranged to:

render the web page to the browser when the web page is not stored in the output cache; and

render the web page to the browser when the web page is not valid.

14. The system of claim 12, wherein the output cache manager determines whether the web page is stored in the output cache by matching the cache parameters of the cache profile associated with the requested web page to caching parameters identified in a cache key stored in the output cache.

15. The system of claim 12, wherein the output cache manager is further arranged to:

generate a cache key for the rendered web page, wherein the cache key identifies caching parameters for the rendered web page; and

store the rendered web page and the cache key in the output cache.

16. The system of claim 12, wherein the output cache manager determines whether the web page is valid by determining whether the web page was modified after the web page was stored in the output cache.

17. The system of claim 12, wherein the output cache manager determines whether the web page is valid by determining whether the web page was stored in the output cache longer than a predetermined time duration.

18. A computer-readable storage medium having computer-executable instructions for managing an output cache, comprising:

receiving a request for a web page associated with a website;

determining a cache profile, wherein the cache profile is separately stored from a web page template of a web page and linked to the web page template via metadata of the cache profile, wherein the cache profile is determined based on the web page hierarchical level location within a website hierarchy of the website, wherein cache parameters of the cache profile and the link between the cache profile and the web page template are modifiable without accessing the web page template;

determining whether the web page is stored in the output cache based on the cache profile;

determining whether the web page is valid when the web page is stored in the output cache; and

returning the web page from the output cache when the web page is stored in the output cache and the output cache is valid.

19. The computer-readable storage medium of claim 18, further comprising:

rendering the web page from a server when the web page is not stored in the output cache; and

rendering the web page from the server when the web page is not valid.
