摘要
The present invention is directed towards a method for using a listening policy for a virtual server on an intermediary device. An intermediary device establishes for a first virtual server a first listening policy with an expression for evaluating packets received by the intermediary device to determine whether the packet may access the first virtual server. The intermediary device listens for packets at a first internet protocol (IP) address and a first port specified for the first virtual server. Then, the intermediary device evaluates the expression of the first listening policy to a first packet received at the first IP address and first port and determines whether to provide the first packet to the first virtual server based on a result of the evaluation.
