http://bugs.winehq.org/show_bug.cgi?id=15393

Summary: winhttp doesn't support proxy connections
           Product: Wine
           Version: 1.1.5
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: winhttp
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

wininet already supports proxy connections but winhttp does not, causing Google
Chrome to not work behind a proxy.

Example tiny apps to compare:

wininet.dll using app, HTTPDemo.exe:

winhttp.dll using app, ALWinHTTPClientDemo.exe, I had to use IP addresses for
this to work on the intranet (?)

I have $http_proxy set to "http://wpad:3128/" and the following registry keys,
as per http://support.microsoft.com/kb/819961
