Abstract

A method and mechanism for servicing a request for a web page from a user over a worldwide computer network using a portal management system. A user transmits a request for a web page with one or more portlets to a portal web server. The portal web server communicates with one or more web providers to obtain content for any portlets on the web page. Each web provider may communicate with one or more content retrievers, or access pre-rendered web pages generated by a performance engine, to retrieve content necessary to render the web page. Each content retriever may communicate with a content provider to obtain content. The portal web server assembles the requested web page using stored information and the appearance and operation of the web page and content supplied by the web provider.

Claims

1. A method for fulfilling a user request for a web page comprising one or more portlets, comprising:

at a portal web server, transmitting one or more first requests for content to one or more web providers, each of the one or more first requests being for content used to render at least one member of the one or more portlets;

at each web provider, wherein when said web provider is not responsible for retrieving and supplying one or more requested contents, transmitting one or more second requests for content to one or more content retrievers, each of the one or more second requests being for a subset of content from one member of the one or more first requests corresponding to a particular subject;

at each content retriever, transmitting one or more third requests for content to one or more content providers;

checking, upon receiving the one or more first requests for content one or more central repositories to determine whether the one or more web pages exist in the one or more central repositories;

retrieving the one or more web pages to assemble one or more requested web page in response to the one or more first requests for content by using information about appearance and operation of the one or more requested web page and any responses obtained from the one or more content providers; and

assembling the web page at the portal web server using information about the appearance and operation of the one or more first, second, or third requests for content, one or more web pages stored at the one or more central repositories, and any responses to the one or more third requests for content.

2. The method of claim 1, wherein at least one of the responses to the one or more third requests for content are customized for the user using a content provider user identifier.

3. The method of claim 1, wherein the step of assembling the web page further comprises incorporated pre-generated content for at least one member of the one or more portlets.

4. The method of claim 1, further comprising:

obtaining data from one or more content providers;

rendering content to be displayed in the one or more portlets according to a pre-determined scheme into one or more web pages; and

storing the one or more web pages in the one or more central repositories.

5. The method of claim 4, further comprising:

associating one or more time stamps with the content to be displayed in one or more portlets; and

determining whether the one or more time stamps have expired.

6. The method of claim 4, in which the content comprises one or more customizations for the user.

7. The method of claim 4, in which the step of rendering content is performed prior to receiving the request for content from the user.

8. The method of claim 4, in which the step of rendering content is performed at one or more pre-configured time intervals.

9. The method of claim 4, in which the one or more web pages to be displayed in a portlet are same for different users.

10. The method of claim 4, in which the one or more web pages to be displayed in the one or more portlets are based in part upon the one or more first requests for content.

11. The method of claim 4, in which the step of rendering the content only renders content for the one or more portlets visited within a specified time.

12. The method of claim 4, in which the step of obtaining data from the one or more content providers is performed at one or more pre-configured time intervals.

13. The method of claim 4, further comprising performing automatic error handling based upon one or more criteria.

14. A computer-readable medium carrying one or more sequences of instructions for fulfilling a user request for a web page comprising one or more portlets, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform the steps of:

at a portal web server, transmitting one or more first requests for content to one or more web providers, each of the one or more first requests being for content used to render at least one member of the one or more portlets by using the information about the appearance and operation of a requested web page;

at each web provider, transmitting one or more second requests for content to one or more content retrievers, each of the one or more second requests for content being for a subset of content from one member of the one or more first requests for content corresponding to a particular subject;

at each content retriever, transmitting one or more third requests for content to one or more content providers;

checking, upon receiving the one or more first requests for content, one or more central repositories to determine whether the one or more web pages exist in the one or more central repositories;

retrieving the one or more web pages to assemble one or more requested web page in response to the one or more first requests for content by using information about appearance and operation of the one or more requested web page and any responses obtained from the one or more content providers; and

assembling the web page at the portal web server using information about the appearance and operation of the one or more first, second, or third requests for content, one or more web pages stored at the one or more central repositories, and any responses to the one or more third requests for content.

15. The computer-readable medium of claim 14, wherein at least one of the responses to the one or more third requests for content is customized for the user using a content provider user identifier.

16. The computer-readable medium of claim 14, wherein the step of assembling the web page further comprises incorporated pre-generated content for at least one member of the one or more portlets.

17. The computer-readable medium of claim 14, in which the steps performed by the one or more processors further comprises:

obtaining data from one or more content providers;

rendering content to be displayed in the one or more portlets according to a pre-determined scheme into one or more web pages; and

storing the one or more web pages in the one or more central repositories.

18. The computer-readable medium of claim 17, in which the steps performed by the one or more processors further comprises:

associating one or more time stamps with the content to be displayed in one or more portlets; and

determining whether the one or more time stamps have expired.

19. The computer-readable medium of claim 17, in which the step of rendering content is performed prior to receiving the one or more first requests for content.

20. The computer-readable medium of claim 17, in which the step of rendering content is performed at one or more pre-configured time intervals.

21. The computer-readable medium of claim 17, in which the step of obtaining data from a content provider is performed at one or more pre-configured time intervals.

22. A system for fulfilling a user request for a web page comprising one or more portlets, comprising:

at a portal web server, means for transmitting one or more first requests for content to one or more web providers, each of the one or more first request being for content used to render at least one member of the one or more portlets by using the information about the appearance and operation of a requested web page;

at a web provider, means for transmitting one or more second requests for content to one or more content retrievers, each of the one or more second requests for content being for a subset of content from one member of the one or more first requests for content corresponding to a particular subject;

at a content retriever, means for transmitting one or more third requests for content to one or more content providers;

means for checking, upon receiving the one or more first requests for content, one or more central repositories to determine whether the one or more web pages exist in the one or more central repositories;

means for retrieving the one or more web pages to assemble one or more requested web page in response to the one or more first requests for content by using information about appearance and operation of the one or more requested web page and any responses obtained from the one or more content providers; and

means for assembling the web page at the portal web server using information about the appearance and operation of the one or more first, second, or third requests for content, one or more web pages at the one or more central repositories, and any responses to the one or more third requests for content.

23. The system of claim 22, wherein at least one of the responses to the one or more third requests for content is customized for the user using a content provider user identifier.
