Hi, I have an existing url_rewrite_program script which redirects the user based on the host they came in on. I also want to redirect the user to different URLs based on their user agent string (for example, if the string has the word "iphone" in it). Does anyone know how I'd accomplish this with a single url_rewrite_program? I've checked out a few squid options, but I haven't found what I'm looking for yet. Should I be using urlgroups or something? I've found some information on how to do this, but no details. For instance, this email says what I'd like to do is possible, but doesn't say how: http://www.squid-cache.org/mail-archive/squid-users/200803/0802.html Thanks, Reuben
