[PATCH 0/2] MR6541: wininet: Only include non-empty session user agent string in request headers.

[Andrew Nguyen (＠arethusa)]

The WordSmith application downloads an update information file with wininet, but it fails to receive the correct data because the remote HTTP server returns a 503 error page, as it does not tolerate receiving a User-Agent header with a blank value in the request.

Tests show that when a blank user agent string is passed to InternetOpen, a request created from the resulting session handle should not include a User-Agent header at all.
