Still struggling with this. As soon as I logged into B from A I lose
control of that session/connection. So $exp->send() won't do anything.
Did you write something like this before. Can I have an example?

Note:  A know B but doesn't know C - in another words, to get to C you have
to go through B.

Thanks a million,
Hailey
