Abstract: Systems and methods are described for using a client agent operating in a virtual private network environment to intercept HTTP communications. Methods include: intercepting at the network layer, by a client agent executing on a client, an HTTP request from an application executing on the client; modifying the HTTP request; and transmitting, via a transport layer connection, the modified HTTP request to a server. Additional methods may comprise adding, removing, or modifying at least one cookie in the HTTP request. Still other methods may comprise modifying at least one name-value pair contained in the HTTP request. Corresponding systems are also described.

Abstract: Systems and methods for reducing file sizes for files delivered over a network are disclosed. A method comprises receiving a first file comprising sequences of data; creating a hash table having entries corresponding to overlapping sequences of data; receiving a second file comprising sequences of data; comparing each of the sequences of data in the second file to the sequences of data in the hash table to determine sequences of data present in both the first and second files; and creating a third file comprising sequences of data from the second file and representations of locations and lengths of said sequences of data present in both the first and second files.

Abstract: A method including communicating with a content server, wherein the communication includes transmitting request data to the content server and receiving first response data associated with the request data; identifying response object data within the first response data; determining whether the response object data is to be downloaded; querying the content server for second response data that corresponds to the response object data based on the determination; transmitting the first response data to a user agent; and storing the second response data, wherein the second response data can be provided to the user agent in a subsequent request.

Abstract: A method and system for providing delta compression, the method includes receiving request data from a user agent, communicating with a content server, wherein the communication includes transmitting the request data to the content server and receiving response data associated with the request data, generating key data associated with the response data, wherein the generated key data represents block data of the response data, storing the generated key data and the block data, and transmitting the block data to the user agent.

Abstract: A system including a user agent configured to transmit request data to a content server, wherein the request data corresponds to a request for a web page; and an optimization server configured to receive a first response data corresponding to the request data from a content server, identify response object data within the first response data, query the content server for second response data that is associated with the identified response object data, and transmit optimized data to the user agent, wherein the contents of the optimized data can include the first response data and the second response data.
