http://forum.directadmin.com – Hi all, I'm using Apache Traffic Server (ATS) for my server, and configure each url in /etc/trafficserver/remap.config Now I want to add some more domains, I see regex_map allow to configure using Regular Expression, but it does not work. So I want to ask if someone has configured this? Thank you very much! (HowTos)
