hopByHopHeaders

protected static final org.apache.http.message.HeaderGroup hopByHopHeaders

These are the "hop-by-hop" headers that should not be copied. http://www.w3.org/Protocols/rfc2616/rfc2616-sec13.html I use an HttpClient HeaderGroup class instead of Set because this approach does case insensitive lookup faster.
