Abstract: A device receives, from a client device, a request for a resource that is available from an origin device, and determines whether the resource is cached in a cache server or not cached in the cache server. The device forwards the request to the cache server regardless of whether or not the resource is cached in the cache server, and receives, when the resource is not cached in the cache server, a redirect command from the cache server based on the request. The device forwards the received redirect command to the client device, where the redirect command instructs the client device to obtain the resource from the origin device. The device receives, from the cache server and based on the request, the resource when the resource is cached in the cache server, and forwards the received resource to the client device.

Abstract: A method for intercepting, by an agent of a client, communications from the client to be transmitted via a virtual private network connection includes the step of intercepting communications based on identification of an application from which the communication originates. The agent receives information identifying a first application. The agent determines a network communication transmitted by the client originates from the first application and intercepts that communication. The agent transmits the intercepted communication via the virtual private network connection.

Abstract: An appliance and method for authorizing a level of access of a client to a virtual private network connection, based on a client-side attribute includes the step of establishing, by an appliance, a control connection with a client upon receiving a client request to establish a virtual private network connection with a network. The appliance transmits, via the control connection, a request to the client to evaluate at least one clause of a security string, the at least one clause including an expression associated with a client-side attribute. The client transmits, via the control connection, a response to the appliance comprising a result of evaluating the at least one clause by the client. The appliance assigns the client to an authorization group based on the result of evaluation of the at least one clause.

Abstract: The intranet IP address management solution of the appliance and/or client described herein provides an environment for efficiently assigning, managing and querying virtual private network addresses, referred to as intranet IP (IIP) addresses of virtual private network users, such as a multitude of SSL VPN users on an enterprise network. The appliance provides techniques and policies for assigning previously assigned virtual private network addresses of a user to subsequent sessions of the user as the user logs in multiple times or roams between access points. This technique is referred to IIP stickiness as the appliance attempts to provide the same IIP address to a roaming VPN user. The appliance also provides a configurable user domain naming policy so that one can ping or query the virtual private network address of a user by an easily referenceable host name identifying the user.

Abstract: A device receives, from a client device, a request for a resource that is available from an origin device, and determines whether the resource is cached in a cache server or not cached in the cache server. The device forwards the request to the cache server regardless of whether or not the resource is cached in the cache server, and receives, when the resource is not cached in the cache server, a redirect command from the cache server based on the request. The device forwards the received redirect command to the client device, where the redirect command instructs the client device to obtain the resource from the origin device. The device receives, from the cache server and based on the request, the resource when the resource is cached in the cache server, and forwards the received resource to the client device.

Abstract: The present invention is related to a method for establishing via an appliance a transport layer protocol connection initiated by a server on a first network to a client connected from a second network to the first network via a secure socket layer virtual private network (SSL VPN) connection. The method includes the step of receiving, by an appliance, a transport layer connection request from a server on a first network to connect to a client connected to the first network via a SSL VPN connection from a second network. The transport layer connection request identifies a client destination internet protocol address and a client destination port on the first network.

Abstract: A method for intercepting communication of a client to a destination on a virtual private network includes an agent executing on the client that intercepts a network communication of the client. The agent provides a virtual private network connection from a first network to a second network. The decision to intercept is based on a network destination description or an identification of an application authorized to be accessed via the virtual private network. In one case, the agent determines that a destination specified by the intercepted communication corresponds to a network identifier and a port of a network destination description of an application on the second network authorized for access via the virtual private network. In response to this determination, the agent transmits the intercepted communication.
