Patch for ijb-202 (apply in ijb directory)
Author: Marc Roessler <marc@tentacle.franken.de>


	IJB now also relays ftp connections of the form
		ftp://host/path/file.txt;
	even authenticated ftp connections of the form
		ftp://user:login@host:port/path/file.txt
	do work now; "user:login@host" is treated as the host
	part, this is not very elegant but works.
	NOTICE:
		IJB does not include any ftp client functions!
		ftp connection relaying only works if the next hop
		is an ftp enabled proxy!



	Another new feature is the treatment of the Accept*
	fields in the http header. The following options can
	be used in the main config file:

		accept <option>
		accept-language <option>
		accept-encoding <option>
		accept-char <option>

	where option can be one of the following:

	     option  | 	effect
	   -------------------------------
		.    |	(pass unmodified)
		-    |	(drop this field)
	     [other] |	(replace field contents sent by browser
		     |   with the string [other])

	(default is: pass unmodified)

	Example:
		accept                  .
		accept-language         en
		accept-encoding         gzip
		accept-char             -

	Use with care!
