since it's skipped by the caller before the URL is passed to this
function.
(process_request): Include code to handle proxy FTP requests as
well. This also lead to a bit of a cleanup in the calling conventions
of extract_http_url function. tinyproxy can handle both types of
resources by skipping the leading :// part.

tinyproxy. There is really no need for this code, since there are
perfectly good programs out there (like rinetd) which are designed for
TCP tunnelling. tinyproxy should be a good HTTP proxy, nothing more,
and nothing less; therefore, the tunnelling code is gone.

It was a one line fix.

tinyproxy. The additional code is in process_request(), but Petr also had to change around some of the other functions (like process_client_headers and handle_connection.) Note: Right now this code has not been tested, but it is believed to work. To enable run ./configure --enable-transparent-proxy

tinyproxy now ignores all the headers after a "double CGI" situation has occurred.
(get_all_headers): Instead of dropping duplicate headers when the "double CGI" situation occurs, tinyproxy will now drop _all_ the headers from the "inner" HTTP response.

and added the get_content_length() function.
The process_server_headers() function was rewritten to remove the
Connection header correctly, and also retrieve the Content-Length value.
This value is needed in the relay_connection() function since there are
some remote machines which do not properly close down the connection once
the body has been retrieved. Thanks to James Flemer for finding a test
case for this problem.

itself to find out all the changes. Changed the process_client_header()
function to use the hashmap and vector modules. I've made this change to
better handle the Connection header. The Connection header, it it's
present, lists all the headers which should _not_ be transmitted any
further along. An HTTP/1.1 proxy must respect this.
Other changes are basically cosmetic.

Added the TUNNEL_CONFIGURED() macro to help with testing for the tunnel

Ignore any blank lines when tinyproxy is expecting a request line.
Instead of sending the request line to the remote server in pieces,
tinyproxy nows sends it in once go. This was done to fix a problem with
some sites like www.heise.de.
Changed all calls to connptr->ssl to connptr->connect_method.
Changed all calls to connptr->send_message to
connptr->send_response_message.
Moved the call to Via header code to inside to the tests to handle if
tinyproxy is sending an error message (don't need to send any headers.)
