Decode BIGIP Cookie

The F5 BIG-IP load balancer uses an encoded cookie to maintain stateful connections from the client to the server. These cookies are automatically sent in every request to the domain that set them. This allows a simple way to track each client’s server association for load balancing control.

This extension reverse the F5 algorithm used to encode the data, and exposes the IP address and TCP port of the host that is actually handling your connection.

It was made to help administrators in trobleshooting situations.

Note that non encrypted cookies are considered a security issue, and this extension will not work if your load balancer was configured to use the non reversible crypto.
