A simple rule like this one for regex_remap.so would suffice . http://$t/$P <http://$t/$P> You would use this in remap.config, like map http://www.example.com <http://www.example.com/> http://real.example.com <http://real.example.com/> @plugin=regex_remap.so @pparam=strip_query.conf More docs to decipher this is available at https://docs.trafficserver.apache.org/en/latest/reference/plugins/regex_remap.en.html <https://docs.trafficserver.apache.org/en/latest/reference/plugins/regex_remap.en.html> But, basically, this rewrites the URL to be just $t - The host as used in the "to" portion of the remap rule $P - The entire path of the request Now, bear in mind that this removes the query parameters from the URL as seen by the origin server. I don’t know if that’s the intent. Also, if you want something more intelligent as you described in the first email, you’d have to create appropriate regexes to match the groups of query parameters you wish to retain. The regexes and group expansion ($0-$9) are Perl compatible. I hope this helps? — Leif > > I can see some enhancement to the url_sig since I would like to use in > conjunction with it.
