You can report bugs and suggest features for WinInet, WinHTTP and HTTP.sys using Microsoft Connect at https://connect.microsoft.com.
Once you login with a passport account, you should be able to go into “Available Program” and sign up for WNDP.
We are currently hosting WinINET, WinHTTP and HTTP.sys on the site. We will be incorporating other programs shortly.
