Not yet, but I have written a couple examples over the years available in
the squid-users archives.

For things to work smoothly you really want to make sure each web server
can accept the exact same URL as the user is requesting from your reverse
proxy. If you need to modify the URL while it is forwarded to the web
server you are likely to sooner or later run into problems due to
mismatches between what your webserver thinks is the correct URL and what
your users actually should be requesting..

If you need to modify the requested URLs then this can be done with a
redirector.
