Abstract

The subject matter of this specification can be embodied in, among other things, a method that includes generating, within a web-accessible document, a parent container document associated with a first Internet domain and one or more child container documents within the parent container document and associated with a second Internet domain. The method also includes receiving, by the parent container document, information requested from a server associated with the first Internet domain, and communicating the information from the first Internet domain to the second Internet domain using the parent container document associated with the first Internet domain to transmit the information to the one or more child container documents associated with the second Internet domain.

Claims

1. A computer-implemented method comprising:

generating, within a web-accessible document, a parent container document associated with a first Internet domain and one or more child container documents within the parent container document and associated with a second Internet domain;

receiving, by the parent container document, information requested from a server associated with the first Internet domain; and

communicating the information from the first Internet domain to the second Internet domain using the parent container document associated with the first Internet domain to transmit the information to the one or more child container documents associated with the second Internet domain.

2. The method of claim 1, wherein the information received by the parent container document is included in a markup language attribute.

3. The method of claim 2, wherein the markup language attribute is selected from a group comprising a source (SRC) attribute, a name attribute, a language attribute, an ID attribute.

4. The method of claim 1, further comprising determining how many child container documents are generated by the parent container document based on a size of the received information.

5. The method of claim 4, wherein the determination comprises comparing the size of the received information to a uniform resource identifier (URI) size limit of a client browser accessing the web-accessible document.

6. The method of claim 5, further comprising fragmenting the received information into fragments that are substantially equal to or less than the URI size limit.

7. The method of claim 6, further comprising generating additional child container documents, each to receive a fragment, until every fragment has a corresponding child container document.

8. The method of claim 1, further comprising requesting the information from the server using a markup language form generated by the parent container document.

9. The method of claim 1, wherein the transmission of the information from the parent container document to the one or more child container documents comprises accessing a library having executable code that fragments the information and distributes the fragmented information to the one or more child container documents.

10. The method of claim 9, wherein the library is hosted at a first server remote from a second server that hosts the web-accessible document.

11. The method of claim 9, further comprising requesting the fragmented information from the one or more child container documents and reassembling the fragmented information for use by an application hosted at the first Internet domain.

12. The method of claim 1, wherein the parent container document and the one or more child container documents comprise markup language frames, inline frames, Xframes, or a combination thereof.

13. The method of claim 1, further comprising specifying for the one or more child container documents a uniform resource identifier of content that has been cached by a browser accessing the web-accessible document.

14. The method of claim 13, wherein the cached content comprises content from the web-accessible document or the entire web-accessible document.

15. The method of claim 13, further comprising padding the uniform resource identifier with at least a portion of the information received from the server.

16. The method of claim 1, further comprising specifying for the one or more child container documents dummy uniform resource identifiers associated with the first Internet domain, wherein the dummy uniform resource identifier is not associated with existing content.

17. The method of claim 16, further comprising padding the dummy uniform resource identifier with at least a portion of the information received from the server.

18. The method of claim 1, wherein the parent and child container documents are not visible when the web-accessible document is displayed by a browser.

19. The method of claim 1, further comprising accessing the information from the one or more child container documents using an application hosted at the first Internet domain.

20. The method of claim 19, wherein the application executed by a browser during viewing of the web-accessible document.

21. The method of claim 1, further comprising specifying for the one or more child container documents a uniform resource identifier of a file used to specify whether a search engine can index content on the second internet domain.

22. A computer-implemented method comprising:

receiving information requested from a first Internet domain at a container document associated with a web-accessible document hosted at a second Internet domain;

generating, using the container document, one or more child container documents that are associated with the second Internet domain; and

passing the information from the container document to the one or more child container documents associated with the second Internet domain for access by the web-accessible document.

23. A system comprising:

a container generator to generate, for a web-accessible document, a parent container document associated with a first Internet domain and one or more child container documents within the parent container document and associated with a second Internet domain;

an interface for receiving, by the parent container document, information requested from a server associated with the first Internet domain; and

means for communicating the information from the first Internet domain to the second Internet domain by transmission of the information from the parent container document to the one or more child container documents.
