I'm using SBB to create a secure tunnel, which has worked great up to now. I've been using 22 and 443(which has fgot round some firewall issues) A client has asked to demp the product recently, and its turned out that both 443 and 80 are running through a proxy server, which means I can't get a connection.Are there any suggested value changes or alterations which would prevent the SSH session being cached on the proxy server, I guess something like a TTL value?

SSH can't be "cached" by a proxy server. What you can do is use WebTunneling capabilities of SecureBlackbox controls to tunnel your SSH connection via HTTPS proxy.

Further to that, am I right its just a case of setting the usewebtunneling, webtunneladdress and webtunnel port properties to their respective vales, or do I need to do anything additional?

Yes, you basically need to set only the mentioned properties.

Do I need to change anything else? When I set these I can't get a connection to my ssh server.

You should not need anything else.
What you can do is use TElHTTPSClient to try to connect to some known web site via WebTunneling functionality. This will let you know that the proxy works as expected and tunnels the connection. If it doesn't, then you need to talk to your network admin regarding the settings.

It can be anything. As said, we need to ensure that the proxy itself works, then we can go further and investigate SSH-specific aspects.

OK, I've used your Http/Https cleint demo to test this out. I loaded the demo, changed usewebtunnelling to true, webtunneladdress to my proxy ip and webtunnelport to the proxy port. I then run the demo and try going to a standard site. I get a -1 connection error.

Where next?
