HTTP proxy and HTTP connections

• A HTTP connection is divided in four parts: request-headers, request-body, response-headers and response-body

• HTTP::Proxy can therefore look at/modify the data in four different places and in two different ways (headers/body)

• You know Unix, so you know the power of:

      grep | cut | sort | nl

• HTTP::Proxy also uses filters that modify a flow of data (for the message bodies). They also can be stacked, which brings you the power to forever alter the face of the web (!!!)
