Create a connection between the two requests (nodes) and register an optional callback to process in between
transmissions of the source and destination request. Leverage this functionality to handle situations such as
challenge response systems. The session class maintains a top level node that all initial requests must be
connected to. Example::
sess = sessions.session()
sess.connect(sess.root, s_get("HTTP"))
If given only a single parameter, sess.connect() will default to attaching the supplied node to the root node.
This is a convenient alias and is identical to the second line from the above example::
sess.connect(s_get("HTTP"))
If you register callback method, it must follow this prototype::
def callback(session, node, edge, sock)
Where node is the node about to be sent, edge is the last edge along the current fuzz path to "node", session
is a pointer to the session instance which is useful for snagging data such as sesson.last_recv which contains
the data returned from the last socket transmission and sock is the live socket. A callback is also useful in
situations where, for example, the size of the next packet is specified in the first packet. As another
example, if you need to fill in the dynamic IP address of the target register a callback that snags the IP
from sock.getpeername()[0].
