Add ? to quantifiers to 51 # switch back to greedy. 52 # 53 # 'T' (trivial) prevents parsing for backreferences in the substitute. 54 # Use if you want to include text like '$&' in your substitute without 55 # quoting. 56 # 57 # 'D' (Dynamic) allows the use of variables. Supported variables are: 58 # $host, $listen-address, $origin (the IP address the request came 59 # from), $path and $url. 60 # 61 # Note that '$' is a bad choice as delimiter for dynamic filters as you 62 # might end up with unintended variables if you use a variable name 63 # directly after the delimiter. Variables will be resolved without 64 # escaping anything, therefore you also have to be careful not to chose 65 # delimiters that appear in the replacement text. For example '<' should 66 # be save, while '?' will sooner or later cause conflicts with $url. 67 # 68 ################################################################################# 69 70 71 ################################################################################# 72 # 73 # js-annoyances: Get rid of particularly annoying JavaScript abuse. 74 # 75 ################################################################################# 76 FILTER: js-annoyances Get rid of particularly annoying JavaScript abuse. 77 78 # Note: Most of these jobs would be safer if restricted to a 79 # <script> context as in: 80 # 81 # s/(<script.*)nasty-item(?=.*<\/script>)/$1replacement/sigU 82 # 83 # but that would make them match only the first occurrence of 84 # nasty-item in each <script>.
