Some points:
1)
http://wiki.squid-cache.org/SquidFaq/ReverseProxy
2) you overlook the far better method of redirection: deny_info + ACL
to perform HTTP protocol level redirects where needed. Based on any ACL
criteria. With a client-visible redirect so headers and body etc are all
updated correctly.
3) redirector method of doing it is WORST practice possible.
HTTP headers and body content often contain the hostname/port the
webserver thinks is being used. With redirect this is no longer the
publicly visible ones and things die badly very quickly. The debug_redir
does not help identify these problems in any way.
You also seem to have a very perl-centric view of redirectors. They
are applications, unlimited by coding language or method of operation.
There are popular redirectors out there that do things far more powerful
than alter URL (ie http://www.ex-parrot.com/pete/upside-down-ternet.html)
