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 multiplexing 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 multiplexes requests from one or more applications via the same transport layer connection maintained by the acceleration program. As such, the acceleration program can utilize the idle time of one application in using the transport layer connection to service a request of a second application through the same transport layer connection.

A method for accelerating on a client access by the client to one or more applications on a server by multiplexing a plurality of application requests via a shared transport layer connection, the method comprising the steps of: (a) intercepting at a layer below an application layer of a network stack of a client, by an acceleration program on the client, a first request by a first application of the client to access a server;(b) transmitting, by the acceleration program, the first request via a transport layer connection established between the acceleration program and the server;(c) intercepting at the layer below the application layer, by the acceleration program, a second request by a second application of the client to access the server;(d) determining, by the acceleration program, that the established transport layer connection is not currently in use by the first application based on expiration of a predetermined period of time without communication by the first application; and(e) transmitting, by the acceleration program, the second request via the established transport layer connection used by the first application, responsive to the determination that the established transport layer connection is not currently in use by the first application. 2. The method of claim 1, further comprising transmitting, by the acceleration program, the second request upon receiving a response to the request of the first application from the server. 3. The method of claim 1, wherein step (d) further comprises: determining, by the acceleration program, that the established transport layer connection is currently in use by the first application;waiting, by the acceleration program and responsive to determining that the established transport layer connection is currently in use by the first application, the predetermined period of time; anddetermining, by the acceleration program, responsive to the expiration of the predetermined period of time, that the established transport layer connection is not currently in use by the first application. 4. The method of claim 1, further comprising determining, by the acceleration program, the first application is not currently using the transport layer connection by comparing a number of bytes transmitted by the first application to the server with a number of bytes acknowledged by the server, andwherein a protocol of the transport layer connection provides for acknowledging receipt of bytes. 5. The method of claim 1, further comprising determining, by the acceleration program, the first application is not currently using the transport layer connection by checking a length of message identifier in a message between the client and the server. 6. The method of claim 1, further comprising multiplexing, by the acceleration program, requests from a plurality of applications on the client via the transport layer connection. 7. The method of claim 1, further comprising pooling, by the acceleration program, a plurality of transport layer connections to the server for use by a plurality of applications of the client. 8. The method of claim 1, further comprising transmitting, by an appliance, the acceleration program to the client upon a request from the client to establish a connection to the server. 9. The method of claim 1, further comprising upon receipt of the acceleration program, automatically installing and executing, by the client, the acceleration program. 10. The method of claim 1, wherein the acceleration program further comprises a filter device driver interfaced to a transport layer of a network stack of the client. 11. The method of claim 1, further comprising performing, by the acceleration program, one of the following acceleration techniques: compression;decompression;Transport Control Protocol buffering; andcaching. 12. The method of claim 1, further comprising performing, by the acceleration program, one of encryption or decryption of communications between the client and the server. 13. The method of claim 1, further comprising closing, by the acceleration program, the transport layer connection upon receipt of one of a reset or finish command for the first application and the second application. 14. The method of claim 1, wherein step (b) further comprises establishing the transport layer connection between the acceleration program and an appliance, the appliance in communications with the server. 15. The method of claim 14, further comprising establishing, by the appliance, a pool of one or more transport layer connections for use by the acceleration program. 16. The method of claim 14, further comprising multiplexing, by the appliance, via the pool of one or more transport layer connections a plurality of communications between the acceleration program and the server. 17. The method of claim 1, further comprising executing, by the client, the acceleration program, transparently to one of a network layer, a session layer, or an application layer of a network stack of the client. 18. The method of claim 1, further comprising executing, by the client, the acceleration program, transparently to one of the first application, the second application, or the server. 19. A system for accelerating on a client access by the client to one or more applications on a server by multiplexing a plurality of application requests via a shared transport layer connection, the system comprising: means for intercepting at a layer below an application layer of a network stack of a client, by an acceleration program on the client, a first request by a first application of the client to access a server;means for transmitting, by the acceleration program, the first request via a transport layer connection established between the acceleration program and the server;means for intercepting at the layer below the application layer, by the acceleration program, a second request by a second application of the client to access the server;means for determining, by the acceleration program, that the established transport layer connection is not currently in use by the first application based on comparing a number of bytes transmitted by the first application to the server with a number of bytes acknowledged by the server; andmeans for transmitting, by the acceleration program, the second request via the established transport layer connection used by the first application, responsive to the determination that the established transport layer connection is not currently in use by the first application. 20.
