Proxying is unusable in this case, due internal architecture. I put 
data to SSL_plugin and it sending data to wires without my 
interception.

However it have a solution. See for httpsend for inspiration. When 
HTTP client needs to use HTTPS and needs to use proxy too, then it 
connect to proxy server (instead of real client), tell to proxy what 
you want (make a tunnel to specified IP...), and if it is OKI, then 
you have HTTP tunnel and youc an send what you want, include crypted 
traffic.

You can do this by similar way. Contect HTTPproxy by yourself, made 
'CONNECT' method to desired target system, and if it is OK, then 
start SSH session on opened socket connection.
