Abstract
Techniques for suspending a TCP three-way handshake, offering the partial connection to an L-7 application or module at a proxy to perform further processing, and then allowing the L-7 application or module to instruct the proxy's network kernel to perform various actions are described. In various embodiments these actions may include: silently dropping the connection, verbosely rejecting the connection, accepting and processing the connection locally, or forwarding the connection to another proxy or the original destination. This additional functionality is provided, in one particular embodiment, via extensions to the POSIX socket API.
