Is it really necessary to escape dots and hyphens? That depends on what you want it to match. Dot (.) and hyphen (-) have special meanings in regex, so if you want to match those exact characters in the input, then yes you need to \-escape them. > And, will > the $ really makes it verify from the right to the left ? > Huh? never heard "verify" in regards to regex. If you mean scan, that is something your OS regex library implementation may or may not do. Dollar ($) is the end-anchor, the pattern is only a match if the ending of the URL is at that position in relation to the rest of the pattern pieces. FYI: none of this has anything particular to do with Squid. It is basic regular expressions. You should lookup a beginners guide to regular expressions for these answers and many other useful things about regex.
