The present invention is directed towards systems and methods for dynamically deploying and executing acceleration functionality on a client to improve the performance and delivery of remotely accessed applications. In one embodiment, the client-side acceleration functionality is provided by an acceleration program that performs a transport layer connection pooling technique for improving performance of communications and delivery of a remotely-accessed application. The acceleration program establishes a transport layer connection from the client to the server that can be used by multiple applications on the client, or that is otherwise shared among applications of the client. The acceleration program maintains the transport layer connection open to reduce the number of transport layer connection requests and number of transport layer connections established with the server for an application or multiple applications running on the client.

The method of claim 1, comprising transmitting, by an appliance, the acceleration program to the client upon a request from the client to establish one of a connection or a session with the server. 3. The method of claim 2, comprising upon receipt of the acceleration program, automatically installing and executing, by the client, the acceleration program. 4. The method of claim 1, wherein the acceleration program comprises a filter device driver interfaced to a transport layer of a network stack of the client. 5. The method of claim 1, comprising multiplexing, by the acceleration program, requests from a plurality of applications on the client via the established transport layer connection. 6. The method of claim 1, comprising performing, by the acceleration program, on the client one of the following acceleration techniques: compression;decompression;Transmission Control Protocol multiplexing;Transmission Control Protocol buffering; andcaching. 7. The method of claim 1, comprising performing, by the acceleration program, one of encryption or decryption of communications between the client and the server. 8. The method of claim 1, comprising closing, by the acceleration program, the first transport layer connection upon receipt of a reset or finish command. 9. The method of claim 1, comprising maintaining, by the acceleration program, the transport layer connection open during a period of idle activity between the server and one of the first application or the second application. 10. The method of claim 9, comprising inserting, by the acceleration program, in a communication from the client to the server an instruction to keep the transport layer connection open. 11. The method of claim 1, comprising determining, by the acceleration program, the transport layer connection is currently being used by one of the first application or the second application by comparing the number of bytes transmitted to and acknowledged from the server for each application. 12. The method of claim 1, further comprising determining, by the acceleration program, the transport layer connection is currently being used by the first application, and opening a second transport layer connection between the acceleration program and the server for use by the second application. 13. The method of claim 1, wherein establishing the transport layer connection further comprises establishing the transport layer connection between the acceleration program and an appliance, the appliance in communications with the server. 14. The method of claim 13, comprising establishing, by the appliance, a pool of one or more transport layer connections for use by the acceleration program. 15. The method of claim 1, comprising executing, by the client, the acceleration program, transparently to one of a network layer, a session layer, or application layer of a network stack of the client. 16. The method of claim 1, comprising executing, by the client, the acceleration program, transparently to one of the first application, the second application, or the server. 17. A system for accelerating access by the client to one or more servers by pooling on the client one or more transport layer connections to the server, the system comprising: means for intercepting, by an acceleration program on the client, a first request by a first application to establish a first transport layer connection with a server;means for establishing, by the acceleration program, a transport layer connection between the acceleration program and the server;means for intercepting, by the acceleration program, a second request by a second application to establish a second transport layer connection with the server;means for determining, by the acceleration program based on a content length parameter or a chunk-size field in an application layer communication between the first application and the server, that the communication between the first application and the server is complete and the first application's use of the established transport layer connection is idle; andmeans for using, by the acceleration program, the established transport layer connection to provide the requested transport layer connection for the second application. 18. The system of claim 17, comprising means for automatically installing and executing, by the client, the acceleration program. 19. The system of claim 17, comprising an appliance transmitting the acceleration program to the client upon a request from the client to establish one of a connection or a session with the server. 20. The system of claim 17, wherein the acceleration program comprises a filter device driver interfaced to a transport layer of a network stack of the client. 21. The system of claim 17, comprising means for multiplexing, by the acceleration program, requests from a plurality of applications on the client via the second transport layer connection. 22.
