Subject: get_destination_from_headers(): Additionally update the request line in proxy format
X-Git-Tag: v_3_0_24~64
X-Git-Url: http://www.privoxy.org/gitweb/%40default-cgi%40toggle?a=commitdiff_plain;h=7cc90f68ad18699fd25d311afc4e6dc48fb92469;p=privoxy.git

get_destination_from_headers(): Additionally update the request line in proxy format

This makes rewriting intercepted requests more convenient.

Previously it was expected to fail unless $hostport
was being used, but rewrites of intercepted requests
without $hostport failed "the wrong way" and would
result in an out-of-memory message (vanilla host patterns)
or a crash (extended host patterns).

Reported by "Guybrish Threepwood" in #1694.
