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.

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