I'm using WinHTTP, direct API, and cannot use anything else, so please don't
tell me to use some other API process.

I have code to use a proxy however, I dont have a proxy to test with yet, so
I'm preparing the code but not clear if it's correct. When using the
proxy, I have the following.

==[ Example 1 ]==============================
hSession =
WinHttpOpen(T2OLE(AGENT_NAME),
( szProxyName.length()>0 ) ?
WINHTTP_ACCESS_TYPE_NAMED_PROXY : WINHTTP_ACCESS_TYPE_NO_PROXY,
( szProxyName.length()>0 ) ?
T2OLE(szProxyName.c_str()) : WINHTTP_NO_PROXY_NAME,
WINHTTP_NO_PROXY_BYPASS,
0);


if(bResults && dwProxyAuthScheme)
bResults = WinHttpSetCredentials( hRequest,
WINHTTP_AUTH_TARGET_PROXY,
dwProxyAuthScheme,
T2OLE(szProxyUserName.c_str()),
T2OLE(szProxyPassword.c_str()),
NULL );
==========================================

I recently found out the port may be different so I went and looked and
their is no place to put the port, but I'm assuming I can pass it in with
the proxy name (e.g. proxyname:85). While looking to see if this is
correct I ran across this which made me think, I may be doing the whole
proxy with WinHTTP incorrectly, but realize it also may just be another way
to do it, but neither is particularly the wrong way. I didn't see with
this way how to set user/pass unless it's to use the same
WinHttpSetCredentials like above.

==[ Example 2 ]==============================
WINHTTP_PROXY_INFO proxyInfo;
proxyInfo.dwAccessType = WINHTTP_ACCESS_TYPE_NAMED_PROXY;
proxyInfo.lpszProxy = L"proxy_name";
proxyInfo.lpszProxyBypass = L"<local>";

// Set the proxy information for this session.
WinHttpSetOption( hSession, WINHTTP_OPTION_PROXY,
&proxyInfo, sizeof(proxyInfo));

=========================================

Can someone clear this up so I can have a better understanding of proxies
with WinHTTP?

Is this a question that can't be answered by the mighty C++ developers of
the world!? :)

You only waited 14 hours before whining. It takes longer than that for
newsgroup postings to wrap around the world and come back.

Your second case seems designed only for proxies that do not require
authentication.

Wouldn't it be quicker just to set up a proxy? It wouldn't take you more
than a couple of hours to set up a dedicated machine with a simple proxy
server. Then you could watch this process in real life.
