Abstract: A method of distributing content to an application from a server is disclosed. The method includes detecting in a file to be sent to the application from the server that the application is directed to request one or more resources to be downloaded to the application. A network latency associated with the downloading of the one or more resources is determined. A subset of the one or more resources is selectively packaged based at least in part on the network latency. The selectively packaged subset of the one or more resources is sent to the application.

Abstract: Tracking web content updates is disclosed. An indication that a web content has been updated is received. It is tracked that the web content has been updated. An update to a client that a version of the web content stored in a web browser cache of the client is no longer valid is provided.

Abstract: Identifying content correlation is disclosed. At an intermediary server, requests for a requested dynamic content are monitored. Responses to the requests are monitored. It is determined that a corresponding content component of the requested dynamic content in a plurality of the responses to the requests are correlated. A new request for the requested dynamic content is received. A cached version of the correlated content component is provided in response to the new request.

Abstract: Expediting content delivery is disclosed. A request for content is received from a requestor. A cached component of the requested content that includes at least some cached executable content is identified. The cached component of the requested content is provided to the requestor for provisional execution. It is determined whether a change, if any, in the requested content may invalidate the provisional execution. In the event it is determined that the change in the requested content may invalidate the provisional execution, the requestor is instructed to abandon the provisional execution.

Abstract: A method of transmitting content from a server to a client executing an application is disclosed. A request from a client for a file that includes content related to executing an application is received. The request is responded to by transmitting a modified file that includes initial portions of the file that are sufficient to permit initial functioning of the application, wherein the modified file is formatted with at least one placeholder for remaining portions of the file. The application can begin to access the initial portions of the file by accessing the modified file. The application can access the remaining portions of the file using the at least one placeholder.

Abstract: A method of updating a document object model (DOM) is disclosed. A request by a web browser for information to update the DOM is intercepted by intercepting an interaction with the DOM. The request is converted to a server request as part of a client-server protocol, requesting at least a portion of the information from a server. The server request is sent to the server. A first server response including at least a portion of the information from the server is received. The first server response is processed according to the client-server protocol to determine a first update to the DOM. The first update is applied to the DOM.

Abstract: A method of updating a document object model (DOM) is disclosed. A message is received from a web browser requesting for information to update the DOM. A dummy response message is sent to the web browser, wherein the dummy response message does not include the information to update the DOM, and wherein the dummy response message causes the web browser to create a dummy node in the DOM. A request message is received from a client as part of a client-server protocol, wherein the request message requests at least a portion of the information to be sent to the client. A first response message is sent including at least a portion of the information to the client, wherein the first response message is processed by the client to determine a first update to the DOM, and wherein the first update is applied to the DOM.

Abstract: Producing a modified document object model structure is disclosed. A desired webpage is requested. An alternative webpage is received in response to the request instead of an original version of the desired webpage to be rendered. The alternative webpage is processed. Program code included in the alternative webpage is utilized to request the original version of the desired webpage. The original version of the desired webpage is received. The modified document object model structure different from an original document object model structure corresponding to the received original version of the desired webpage is produced.

Abstract: A method of transmitting content from a server to a client executing an application is disclosed. A request from a client for a file that includes content related to executing an application is received. The request is responded to by transmitting a modified file that includes initial portions of the file that are sufficient to permit initial functioning of the application, wherein the modified file is formatted with at least one placeholder for remaining portions of the file. The application can begin to access the initial portions of the file by accessing the modified file. The application can access the remaining portions of the file using the at least one placeholder.

Abstract: Processing a purge request is disclosed. The purge request is received. An availability state for each content distribution node in a group of content distribution nodes is tracked. Based on the purge request, one or more purge instructions are generated for one or more available state content distribution nodes of the group. Based on the purge request, one or more queued purge instructions are queued for one or more unavailable state content distribution nodes of the group. It is determined that the one or more available state content distribution nodes of the group have completed processing the one or more purge instructions generated for the one or more available state content distribution nodes. Based at least in part on the queuing of the one or more queued purge instructions for the one or more unavailable state nodes, an indication that the purge request has been completed is authorized.
