In an earlier blog (http://blogs.msdn.com/wndp/archive/2005/09/27/474679.aspx), Shivakumar introduced the Connect program. Shiva mentioned WinInet, WinHTTP and HTTP.sys are using Microsoft Connect. This blog is to announce Winsock has now joined Connect. This means you can submit bugs, submit feature requests and (in the future) download additional Winsock-related content such as whitepapers.
Connect Program Homepage: https://connect.microsoft.com.
See Shiva's blog for instructions for how to get started.
