Call to PUTTY.EXE with proxy

Hi,

v3.3.0 build 177 - when calling PUTTY.EXE (v0.53b), the proxy server settings aren't placed into the "WinSCP temporary session" session file. The proxy type is always set to "none" and thus fails to connect,

I believe that proxy options are exported as well. But I cannot try, as I do not have any proxy. Can you post reqistry key with the exported session settings? The key is: To export it to file tempsession.reg, you may use this command:
Of course, you may remove any sensitive information.

I spotted that the Proxy type was wrong by running PUTTY.EXE separately and loading the "WinSCP Temp Session" session in its session menu. You could easily do the same to test this out even if you don't have a proxy.

Aha - ProxyMethod should be ProxyType, and should be 1 not 3 for HTTP. I created a new session in PUTTY.EXE and saved it, then looked in the registry:

OK, I see it. WinSCP saves configuration in format used by latest development snapshot of Putty. It uses ProxyMethod parameter. Last release of Putty (0.53b) uses ProxyType and ProxySOCKSVersion parameters instead. I think I can save all three parameters to support both versions of Putty. Meanwhile, try to use LDS version of Putty.

Thanks, the LDS version is fine.
