Hello,
I have a project requiring the set-up of an proxied ssh session using
PuTTY. I have successfully achieved this where there is a single proxy
(secnario A below) but I need to get it working where there is a chain
of two proxies (scenario B below).
What I'd appreciate is if I could be told how to configure PuTTY to use
a proxy chain, if this is at all possible.
Thank you,
Trib.

Scenario A
----------
This scenario is implemented and works fine.
Client has an internet firewall which prohibits all outgoing connections
except HTTP Port 80. We want to provide SSH access to a remote server
host via the internet. The only port accessible from outside the remote
network is the HTTP port 80 that is attached to an Apache web server
that understands HTTP connect, and proxies a connection to the ssh server:
Client's Network Server Host Network
+-----------+ +---------------------------+
+-----------+ |I| +-----------+ +-----------+
| | |N| | | | |
| PUTTY SSH |->-|T|->-| APACHE |->-| SSH |
| CLIENT | |E| | HTTP | | SERVER |
| | |R| | SERVER | | PORT 22 |
| | |N| | (PORT 80) | | |
| | |E| | | | |
+-----------+ |T| +-----------+ +-----------+
The Putty SSH Client is configured to connect to the SSH server port 22
using the Apache server as a HTTP proxy. The Apache server supports the
"AllowConnect 22" proxying method to allow connections to the SSH server.
Scenario B
----------
The client is installing a web proxy and all outgoing connections will
need to go via this proxy. Only outgoing connections to ports 80 and 443
will be allowed.
Client's Network Server Host Network
+---------------------------+ +---------------------------+
+-----------+ +-----------+ |I| +-----------+ +-----------+
| | | | |N| | | | |
| PUTTY SSH |->-| LOCAL |->-|T|->-| APACHE |->-| SSH |
| CLIENT | | INTERNET | |E| | HTTP | | SERVER |
| | | PROXY | |R| | SERVER | | PORT 22 |
| | | (PORT 80) | |N| | (PORT 80) | | |
| | | | |E| | | | |
+-----------+ +-----------+ |T| +-----------+ +-----------+
How do I configure such a proxy chain in Putty ?
