Abstract: Systems and methods are described for using a client agent operating in a virtual private network environment to intercept HyperText Transfer Protocol (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: A method for allowing or denying, by an appliance, access to a resource by an application on a client via a virtual private network connection includes basing the decision to allow or deny access on identification of the application. The appliance intercepts a request from an application on a client on a first network to access via a virtual private network connection a resource on a second network. The appliance identifies the application and associates with the intercepted request an authorization policy based on the identity of the application. The appliance determines, using the authorization policy and the identity of the application, to either allow or deny access by the application to the resource.

Abstract: Systems and methods are described for using a client agent to manage HTTP authentication cookies. One method includes intercepting, by a client agent executing on a client, a connection request from the client; establishing, by the client agent, a transport layer virtual private network connection with a network appliance; transmitting, by the client agent via the established connection, an HTTP request comprising an authentication cookie; and transmitting, by the client agent via the connection, the connection request. A second method includes intercepting, by a client agent executing on a client, an HTTP communication comprising a cookie from an appliance on a virtual private network to the client; removing, by the client agent, the cookie from the HTTP communication; storing, by the client agent, the received cookie; transmitting, by the client agent, the modified HTTP communication to an application executing on the client; intercepting, by the client agent, an HTTP request from the client; inserting, by the client agent in the HTTP request, the received cookie; and transmitting the modified HTTP request to the appliance. Corresponding systems are also described.

Abstract: In a method and system for routing packets between clients, a packet is received from a first client connected to a secure sockets layer virtual private network (an SSL/VPN) network appliance. An identification is made, responsive to an inspection of the received packet, of i) a type of connection required for transmission of the received packet to a destination address identified by the received packet and ii) a second client connected via an SSL/VPN connection to the SSL/VPN network appliance and associated with the identified destination address. A request is made for establishment by the second client of a connection of the identified type within the SSL/VPN connection. The received packet is transmitted to the second client via the established connection of the identified type.

Abstract: The present disclosure relates to methods and systems for performing response based cache redirection to a cache proxy. A device intermediary to a plurality of clients and a plurality of servers and in communication with a plurality of cache proxies, receives a request for content from a client. The request is for content from a server of the plurality of servers. The device forwards the request to the server. The device identifies a cache redirection policy that specifies an amount of bytes of a response to buffer to calculate a signature of the content of the response. The device computes the signature of the content of the response based on the amount of bytes of the response received from the server and buffered by the device. The device selects a cache proxy based on the computed signature and forwards the request of the client to the selected cache proxy.

Abstract: The present disclosure presents systems and methods for policy based redirection of network traffic, by an intermediary device, to a horizontally deployed WAN device. An intermediary receives a request from a client to access a server. The request was previously modified by a first WAN device to include information in a first option field of a transport layer. The intermediary may determine, responsive to a redirection policy, to send the request to a second WAN optimization device deployed horizontally from the intermediary, instead of the server. The intermediary transmits the request to the second WAN optimization device, while maintaining the information from the first option field. The intermediary device receives the request including the information in the first option field identifying the first WAN optimization device to the second WAN optimization device. The intermediary receives a modified request from the second WAN device, the modified request determined by the intermediary to be sent to the destination server.
