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:

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

generating, using the parent container document, a plurality of child container documents that are associated with the second Internet domain;

fragmenting the received information into fragments, and passing the fragments of the received information from the container document to the plurality of child container documents associated with the second Internet domain for access by the web-accessible document; and

generating another child container document that stores information indicating, at least, a number of child container documents across which the received information has been fragmented and an order for reassembling the fragments of the received information.

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

3. A computer-implemented method comprising:

generating, within a web-accessible document, a parent container document associated with a first Internet domain;

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

determining a number of child container documents to generate by the parent container document based on a size of the received information, 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;

fragmenting the received information into fragments that are equal to or less than the URI size limit;

communicating, by the parent container, the received information from the first Internet domain to a second Internet domain by generating child container documents, each to receive a fragment, until each of the fragments has a corresponding child container document, wherein the child container documents are generated within the parent container document and are associated with the second Internet domain, and transmitting the fragments of the received information to the generated child container documents;

generating another child container document that stores information indicating, at least, the number of child container documents across which the received information has been fragmented and an order for reassembling the fragments;

determining, by a process that is associated with the second Internet domain and that is permitted to access the child container documents but not the parent container document, and by repeatedly polling for the existence of at least one of the child container documents, whether the received information has been communicated to the second Internet domain; and

in response to determining that the received information has been communicated to the second Internet domain, retrieving from the child container documents, by the process associated with the second Internet domain, the information received from the server associated with the first Internet domain.

4. The method of claim 3, wherein the information received by the parent container document is included in a markup language attribute.

5. The method of claim 4, wherein the markup language attribute is selected from a group comprising a source (SRC) attribute, a name attribute, a language attribute, an ID attribute.

6. The method of claim 3, further comprising requesting the information from the server using a markup language form generated by the parent container document.

7. The method of claim 3, wherein the transmission of the information from the parent container document to the child container documents comprises accessing a library having executable code that fragments the information and distributes the fragmented information to the child container documents.

8. The method of claim 7, wherein the library is hosted at a first server remote from a second server that hosts the web-accessible document.

9. The method of claim 7, further comprising requesting the fragmented information from the child container documents and reassembling the fragmented information for use by an application hosted at the first Interact domain.

10. The method of claim 3, wherein the parent container document and the child container documents comprise markup language frames, inline frames, Xframes, or a combination thereof.

11. The method of claim 3, further comprising specifying for the child container documents a uniform resource identifier of content that has been cached by a browser accessing the web-accessible document.

12. The method of claim 11, wherein the cached content comprises content from the web-accessible document or the entire web-accessible document.

13. The method of claim 11, further comprising padding the uniform resource identifier with at least a portion of the information received from the server.

14. The method of claim 3, further comprising specifying for the 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.

15. The method of claim 14, further comprising padding the dummy uniform resource identifier with at least a portion of the information received from the server.

16. The method of claim 3, wherein the parent and child container documents are not visible when the web-accessible document is displayed by a browser.

17. The method of claim 3, further comprising accessing the information from the child container documents using an application hosted at the first Internet domain.

18. The method of claim 17, wherein the application executed by a browser during viewing of the web-accessible document.

19. The method of claim 3, further comprising specifying for the 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.

20. The method of claim 3, wherein the other child container document is generated after each of the additional child container documents have been generated;

and wherein repeatedly polling for the existence of the at least one of the child container documents comprises repeatedly polling for the existence of the other child container document, and

wherein existence of the other child container document indicates that the received information has been transferred to each of the additional child container documents.

21. A system comprising:

a computer-readable storage device that stores instructions; and

one or more processors that are configured to executed the stored instructions, wherein execution of the stored instructions causes the one or more processors to provide;

an interface to receive information requested from a first Internet domain at a parent container document associated with a web-accessible document hosted at a second Internet domain; and

a container generator to;

generate, using the parent container document, a plurality of child container documents that are associated with the second Internet domain;

fragment the received information into fragments, and pass the fragments of the received information from the container document to the plurality of child container documents associated with the second Internet domain for access by the web-accessible document; and

generate another child container document that stores information indicating, at least, a number of child container documents across which the received information has been fragmented and an order for reassembling the fragments of the received information.

22. The system of claim 21, wherein the parent container document and the child container documents comprise markup language frames, inline frames, Xframes, or a combination thereof.

23. A system comprising:

a computer-readable storage device that stores instructions; and

one or more processors that are configured to executed the stored instructions, wherein execution of the stored instructions causes the one or more processors to provide;

an interface for receiving information requested from a server associated with the first Internet domain;

a container generator to generate, for a web-accessible document, a parent container document associated with a first Internet domain and child container documents within the parent container document and associated with a second Internet domain, wherein a number of the generated child container documents is determined based on a size of the received information, 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, wherein the received information is fragmented into fragments that are equal to or less than the URI size limit, and wherein each of the generated child container documents receives a fragment until each of the fragments has a corresponding child container document;

wherein the container generator further generates another child container document that stores information indicating, at least, the number of child container documents across which the received information has been fragmented and an order for reassembling the fragments;

means for communicating the received information from the first Internet domain to the second Internet domain by transmission of the fragments of the received information from the parent container document to the generated child container documents; and

means for determining whether the received information has been communicated to the second Internet domain by repeatedly polling for the existence of at least one of the child container documents, wherein the means for determining is associated with the second Internet domain and is permitted to access the child container documents but not the parent container document.

24. A computer program product comprising a machine-readable storage medium that stores instructions that, upon execution by a processor, cause the processor to perform operations comprising:

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

generating, using the parent container document, a plurality of child container documents that are associated with the second Internet domain;

fragmenting the received information into fragments, and passing the fragments of the received information from the container document to the plurality of child container documents associated with the second Internet domain for access by the web-accessible document; and
