Hi,

I think that if you use the default settings, the same settings of Internet
Explorer (which should be the correct one, or why whould you use Internet
Explorer if it doesn't work) are used. Meaning that if you are using
multi-purpose Proxy (as configured in Internet Explorer, a.k.a SOCKS) it
will be used in the CInternetSession and if you configured a FTP/WEB proxy,
it will be used (again as its been setuped in IE). Sometimes this IE
behavior is unwanted, and thats why you have option to do it manually.

I haven't done it manually so I am unable to help you.

Daniel,  I also am confused by the WinInet handling of proxies.  I'm using
MFC to connect to an ftp site on the other side of a SOCKS proxy. But with on
success.

I've been using INTERNET_OPEN_TYPE_PRECONFIG in my CInternetSession
constructor.  I've tried setting the proxy configuration in both IE4 and
manually in the registry, in several ways.

The weird thing is that IE4 can access the ftp site, but my code can't!

Daniel, what kind of proxy are you using?  What different things have you
tried?

Have you made any progress?

I would appreciate any information you could give me.

Thanks,

David Roussel.

Yes I know, I have had experiences where users have been sitting behind a proxy 
and not being able to use my code, but the ftp program worked.

Not much... it seems to me the documentation is _very_ sparse and misleading, or 
the code is not consistent... or both...
