 Trying to: Connect to msn account using http proxy.

 Steps: I started by creating a simple msn account. Added my username,
 password and in Advance Tab already had messenger.hotmail.com server and
 1863 port. Choose HTTP proxy, defined the proxy name and typed 8080 for
 the proxy port.

 It give the error:
 HTTP/1.1 502 Proxy Error ( The specified Secure Sockets Layer (SSL) port
 is not allowed. ISA Server is not configured to allow SSL requests from
 this port. Most Web browsers use port 443 for SSL requests.  )
 -
 (15:24:29) proxy: Connection attempt failed: HTTP proxy connection error
 502

 Saw in another ticket to change the port to 443. I did so, changed 1863
 for 443. Then it crashed, completely. It seems when it's needed
 authentication and it's not given, pidgin crashes.

 The debug.log contains the connection attempt...
