Abstract

A system and method for associating blocks of Web page content with caching properties are provided. The caching properties may include global caching properties for all blocks of a Web page and/or individual caching properties for each individual block of the Web page. The caching properties may be identified within the code of the Web page content itself, such as within meta-tags. Caching properties may also be linked to client device characteristics. Both client device caching and proxy device caching of Web page content may be enabled, such that if a block of Web page content in the client device'"'"'s cache is invalid, the proxy device'"'"'s cache is checked for the block of Web page content. Thus, a single Web page may be rendered on a client device using blocks obtained from a local cache, a proxy device'"'"'s cache, and blocks obtained from a source of the Web page content.

Claims

1. A method, in a client side data processing system, for processing a portion of a Web page, comprising:

receiving code for a portion of a first Web page, wherein the code breaks the portion of the first Web page into blocks of Web page content, and wherein one or more of the blocks of Web page content have associated caching properties identified in the code;

parsing the code for the portion of the first Web page to identify the blocks of Web page content and their associated caching properties; and

caching, in a client side data processing system cache, content data corresponding to the blocks of Web page content based on the associated caching properties, wherein at least two blocks of Web page content have different caching properties, and wherein at least two portions of content data corresponding to the at least two blocks of Web page content are cached using the different caching properties.

2. The method of claim 1, further comprising:

receiving a request to retrieve a second Web page, different from the first Web page, wherein a first block of Web page content in the second Web page is the same as a second block of Web page content in the first Web page;

determining if a first portion of content data, corresponding to the first block of Web page content in the second Web page that is the same as the second block of Web page content in the first Web page, is present in the client side data processing system cache;

retrieving the first portion of content data from the client side data processing system cache if the first portion of content data is present in the client side data processing system cache; and

rendering the second Web page using the first portion of content data retrieved from the client side data processing system cache.

3. The method of claim 2, further comprising:

determining if the first portion of content data is valid in the client side data processing system cache;

requesting the first portion of content data from a source computing device if the first portion of content data is not present in the client side data processing system cache or is not valid in the client side data processing system cache; and

rendering the second Web page on a client device using the first portion of content data requested from the source computing device.

4. The method of claim 2, wherein the first Web page has block level caching enabled, and wherein the second Web page does not have block level caching enabled.

5. The method of claim 2, wherein the client side data processing system cache is a local cache of a client device.

6. The method of claim 5, further comprising:

determining if the first portion of content data is present in a client side proxy device coupled to the client device if the first portion of content data is not present in the local cache of the client device;

retrieving the first portion of content data from the client side proxy device if the first portion of content data is present in the client side proxy device; and

rendering the second Web page on the client device using the first portion of content data retrieved from the client side proxy device.

7. The method of claim 2, wherein the client side data processing system cache is a cache of a proxy device coupled to a client device that originated a request for the first Web page.

8. The method of claim 1, wherein the associated caching properties has a conditional requirement that identifies an operational characteristic that is required before the caching property is applied to content data for the corresponding block of Web page content.

9. The method of claim 2, further comprising:

retrieving operational characteristic information for the client side data processing system;

comparing the operational characteristic information to the conditional requirement; and

determining if the caching property is to be applied to content data for the corresponding block of Web page content based on results of the comparison.

10. The method of claim 1, wherein the associated caching properties are provided in meta tags within the code of the portion of the Web page.

11. The method of claim 2, wherein the request to retrieve the second Web page originates from a different client device than a client device that requested the first Web page.

12. A computer program product comprising a computer usable medium having a computer readable program, wherein the computer readable program, when executed on a computer, causes the computer to:

receive code for a portion of a first Web page, wherein the code breaks the portion of the first Web page into blocks of Web page content, and wherein one or more of the blocks of Web page content have associated caching properties identified in the code;

parse the code for the portion of the first Web page to identify the blocks of Web page content and their associated caching properties; and

cache, in a client side data processing system cache, content data corresponding to the blocks of Web page content based on the associated caching properties, wherein at least two blocks of Web page content have different caching properties, and wherein at least two portions of content data corresponding to the at least two blocks of Web page content are cached using the different caching properties.

13. The computer program product of claim 12, wherein the computer readable program further causes the computer to:

receive a request to retrieve a second Web page, different from the first Web page, wherein a first block of Web page content in the second Web page is the same as a second block of Web page content in the first Web page;

determine if a first portion of content data, corresponding to the first block of Web page content in the second Web page that is the same as the second block of Web page content in the first Web page, is present in the client side data processing system cache;

retrieve the first portion of content data from the client side data processing system cache if the first portion of content data is present in the client side data processing system cache; and

render the second Web page using the first portion of content data retrieved from the client side data processing system cache.

14. The computer program product of claim 13, wherein the computer readable program further causes the computer to:

determine if the first portion of content data is valid in the client side data processing system cache;

request the first portion of content data from a source computing device if the first portion of content data is not present in the client side data processing system cache or is not valid in the client side data processing system cache; and

render the second Web page on a client device using the first portion of content data requested from the source computing device.

15. The computer program product of claim 13, wherein the first Web page has block level caching enabled, and wherein the second Web page does not have block level caching enabled.

16. The computer program product of claim 13, wherein the client side data processing system cache is a local cache of a client device.

17. The computer program product of claim 16, wherein the computer readable program further causes the computer to:

determine if the first portion of content data is present in a client side proxy device coupled to the client device if the first portion of content data is not present in the local cache of the client device;

retrieve the first portion of content data from the client side proxy device if the first portion of content data is present in the client side proxy device; and

render the second Web page on the client device using the first portion of content data retrieved from the client side proxy device.

18. The computer program product of claim 12, wherein the associated caching properties has a conditional requirement that identifies an operational characteristic that is required before the caching property is applied to content data for the corresponding block of Web page content.

19. The computer program product of claim 13, wherein the computer readable program further causes the computer to:

retrieve operational characteristic information for the client side data processing system;

compare the operational characteristic information to the conditional requirement; and

determine if the caching property is to be applied to content data for the corresponding block of Web page content based on results of the comparison.

20. An apparatus, comprising:

a processor;

a memory coupled to the processor; and

a cache storage coupled to the processor, wherein the memory contains instructions which, when executed by the processor, causes the processor to;

receive code for a portion of a first Web page, wherein the code breaks the portion of the first Web page into blocks of Web page content, and wherein one or more of the blocks of Web page content have associated caching properties identified in the code;

parse the code for the portion of the first Web page to identify the blocks of Web page content and their associated caching properties; and

cache, in the cache storage, content data corresponding to the blocks of Web page content based on the associated caching properties, wherein at least two blocks of Web page content have different caching properties, and wherein at least two portions of content data corresponding to the at least two blocks of Web page content are cached using the different caching properties.
