Abstract

A method and apparatus for obtaining information in a computer network includes requesting information from a server, and determining whether the information has been pre-stored in a server controlled cache. If the requested information has been pre-stored in the cache, the information is retrieved from memory. Otherwise, the information is obtained from the network, and a copy of the requested information is stored in the cache. In one embodiment of the invention, dynamic web pages are delivered to an Internet browser for viewing by a personal computer user.

Claims

1. A method of delivering web pages to an Internet browser, comprising:

receiving, at an Internet server, a request from the Internet browser, for a page on the worldwide web;

determining whether a copy of said requested web page has been previously stored in a cache linked to said server;

if said requested web page has been previously stored in said cache, retrieving a copy of said requested web page from said cache and transmitting said retrieved copy to the Internet browser;

if said requested information has not been previously stored in said cache, retrieving said requested web page from a database application development tool, delivering said requested web page to said Internet browser, and storing a copy of said requested web page in said cache.

2. A method as claimed in claim 1 wherein the web page includes dynamic information.

3. A method as claimed in claim 1 wherein said determining step further comprises:

creating a profile for said requested web page; and

comparing said created profile with an existing profile associated with a web page stored in said cache.

4. A method as claimed in claim 1 wherein, when said created profile corresponds to said existing profile, said causing step further comprises retrieving a copy of said web page associated with said existing profile from said cache and transmitting said copy to said Internet browser.

5. A method as claimed in claim 1 wherein, when said created profile does not correspond to said existing profile, said causing step further comprises retrieving said requested web page from a database application development tool, delivering said retrieved web page to said Internet browser, and storing a copy of said retrieved web page in said cache.

6. A method as claimed in claim 1 wherein said identifier includes a cookies profile.

7. A method as claimed in claim 1 wherein said information in said memory includes a HyperText Markup Language file that describes a page on the world wide web.

8. A method as claimed in claim 1 wherein said request for information includes a Uniform Resource Locator for a page on the world wide web.

9. A method as claimed in claim 8 wherein said request for information includes a cookies profile.

10. A method as claimed in claim 1 wherein said requested information is submitted by a world wide web browser.

11. A method of obtaining information in a computer network, comprising:

receiving a request for information;

determining whether a copy of said requested information is present in a memory linked to said server;

if said requested information is present in said memory, causing a copy of said requested information to be retrieved from said memory;

if said requested information is not present in said memory, causing said requested information to be retrieved from a computer network information source and causing a copy of said retrieved information to be placed in said memory.

12. A method as claimed in claim 11 wherein said retrieved information includes dynamic information.

13. A method as claimed in claim 11 further comprising delivering said retrieved information to a user.

14. A method as claimed in claim 11 wherein said memory is a cache.

15. A method as claimed in claim 11 wherein said computer network is the Internet, and said requested information is a page on the world wide web.

16. A method as claimed in claim 11 wherein said determining step further comprises:

creating an identifier for said request for information; and

comparing said created identifier with at least one identifier that is associated with information in said memory.

17. A method as claimed in claim 16 wherein said identifier includes a cookies profile.

18. A method as claimed in claim 16 wherein said information in said memory includes a HyperText Markup Language file for said world wide web page.

19. A method as claimed in claim 11 wherein said computer network information source is a database application development tool.

20. A method as claimed in claim 11 wherein said request for information includes a Uniform Resource Locator for a page on the world wide web.

21. A method as claimed in claim 20 wherein said request for information includes a cookies profile.

22. A method as claimed in claim 11 wherein said information is requested using a world wide web browser.

23. A computer system capable of obtaining information, comprising:

a computer network information server configured to receive at least one request for information; and

an information retrieval system configured to accept said at least one request for information from said server and to return said requested information to said computer network information server, wherein said information retrieval system is further configured to;

(i) determine whether information responsive to said request for information is located in a memory linked to said computer network information server,

(ii) transmit said information responsive to said request for information to from said memory to said computer network information server if information responsive to said request for information is located in said memory,

(iii) request information responsive to said request for information from a computer network information source if information responsive to said request for information is not located in said memory,

(iv) transmit information received from said computer network information source to said computer network information server; and

(v) store a copy of said information received from said computer network information source in said memory.

24. A method as claimed in claim 23 wherein said retrieved information includes dynamic information.

25. A computer system as claimed in claim 23 wherein said memory includes a cache.

26. A computer system as claimed in claim 25 wherein said computer network is the Internet, and said requested information includes a page on the world wide web.

27. A computer system as claimed in claim 25 wherein said information retrieval system is linked to an Internet server application program interface.

28. A computer system as claimed in claim 25 wherein said information retrieval system is linked to a common gateway interface.

29. A computer system as claimed in claim 25 wherein said computer network information source includes a database application network tool configured to enable computer network users to customize networked information.

30. A computer system as claimed in claim 25 wherein said computer network information source is capable of dynamically creating information responsive to said request for information.

31. A computer system as claimed in claim 25 wherein said information in said memory includes a HyperText Markup Language file for a page on the world wide web.

32. A computer system as claimed in claim 25 wherein said request for information includes a Uniform Resource Locator for a page on the world wide web.

33. A computer system as claimed in claim 32 wherein said request for information includes a cookies profile.

34. A computer system as claimed in claim 25 wherein said requested information is submitted using a world wide web browser.
