You're server is reporting the wrong Content-Length.

"<html><body><h1>Heading</h1><p>Some Text</p></body></html>" is 59
characters

But the server said "Content-Length: 58"

Also, "Connection: keep-alive" is a HTTP/1.0 concept only, but is being
reported on your HTTP/1.1 request/response improperly.
