Subject: [PATCH] Check that we can actually read from network and not just
 connect

When using Cloudflare, as we do for www.wxwidgets.org, the connection
succeeds as long as Cloudflare itself works, but reading later fails if
the real server behind Cloudflare proxy does not, so check if we can
read something from it.
