Abstract

Improving of bandwidth usage and performance for web page caching. Responsive to a subsequent request for a web page, a server only returns the set of web page portions of the requested web page that are not in a browser cache, have expired, and/or have changed.

Claims

1. A method comprising:

receiving, from a requestor a request for a subsequent web page, the request including a first web page set of metadata;

determining a set of current web page portions based, at least in part, on the first web page set of metadata; and

sending the set of current web page portions to the requestor;

wherein;

the subsequent web page includes the set of current web page portions; and

at least the determining step is performed by computer software running on computer hardware.

2. The method of claim 1, further including:

receiving a request for a first web page; and

transmitting the first web page set of metadata.

3. The method of claim 1, wherein the first web page set of metadata includes:

a set of web page portion definitions and a set of caching policies.

4. The method of claim 3, wherein the determining step comprises:

correlating the set of web page portion definitions to a set of web page portions; and

determining that the set of current web page portions has changed or has not been cached.

5. The method of claim 1, wherein a first web page and the subsequent web page are web pages on a domain.

6. The method of claim 5, wherein the first web page is the subsequent web page.

7. A computer system comprising:

a processor set; and

a computer readable storage medium;

wherein;

the processor set is structured, located, connected, and/or programmed to run program instructions stored on the computer readable storage medium; and

the program instructions include;

first program instructions programmed to receive, from a requestor, a request for a subsequent web page, the request including a first web page set of metadata;

second program instructions programmed to determine a set of current web page portions based, at least in part, on the first web page set of metadata; and

third program instructions programmed to send the set of current web page portions to the requestor;

wherein;

the subsequent web page includes the set of current web page portions.

8. The computer system of claim 7, further including:

fourth program instruction programmed to receive a request for a first web page; and

fifth program instruction programmed to transmit the first web page set of metadata.

9. The computer system of claim 7, wherein the first web page set of metadata includes:

a set of web page portion definitions and a set of caching policies.

10. The computer system of claim 9, wherein the second program instructions programmed to determine comprises:

fourth program instructions programmed to correlate the set of web page portion definitions to a set of web page portions; and

fifth program instructions programmed to determine that the set of current web page portions has changed or has not been cached.

11. The computer system of claim 7, wherein a first web page and the subsequent web page are web pages on a domain.

12. The computer system of claim 11, wherein the first web page is the subsequent web page.

13. A method comprising:

caching a first web page to a cache;

submitting a request for a subsequent web page, the request including a first web page set of metadata;

receiving a set of current web page portions; and

stitching together the subsequent web page;

wherein;

the subsequent web page includes the set of current web page portions; and

at least the stitching step is performed by computer software running on computer hardware.

14. The method of claim 13, wherein the stitching step comprises:

retrieving a subset of the first web page from the cache; and

combining the set of current web page portions with the subset of the first web page;

wherein;

the subset of the first web page corresponds to a set of web page portions of the subsequent web page not received in the receiving step.

15. The method of claim 13, wherein the first web page set of metadata includes:

a set of web page portion definitions and a set of caching policies.

16. The method of claim 13, wherein the first web page and the subsequent web page are web pages on a domain.

17. The method of claim 16, wherein the first web page is the subsequent web page.

18. The method of claim 13, further including:

submitting a request for the first web page.

19. The method of claim 13, further including:

storing the set of current web page portions to the cache.

20. The method of claim 19, further including:

deleting from the cache a subset of the first web page corresponding to the set of current web page portions.
