Subject: First problem: if a client sends a Host: header with a different case than
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=677653a89b7cde85033a137d9e012a02c9ef6df4;p=thirdparty%2Fapache%2Fhttpd.git

First problem: if a client sends a Host: header with a different case than
"Host:", the proxy won't see it and it will end up with two Host: headers
with different capitalization.

Second problem: if the proxy connects to a HTTP/0.9 server, the
first line returned will be corrupt because len was tampered with.
