Sorry - not sure which line you are referring to - but, either way, it makes perfect sense! It is a back-reference to the parenthesised expression 'kgp[a-z0-9]*'. As an example - if the requested URI is kgpwed.html then the RewriteCond is checking if kgpwed.shtml exists and if it exists the RewriteRule causes it to be passed to the client instead of kgpwed.html. This can be seen in the trace... With !-f [perdir D:/xampp/htdocs/] RewriteCond: input='kgpwed.shtml' pattern='!-f' => matched [perdir D:/xampp/htdocs/] rewrite 'kgpwed.html' -> 'kgpwed.shtml' With -f [perdir D:/xampp/htdocs/] RewriteCond: input='kgpwed.shtml' pattern='-f' => not-matched [perdir D:/xampp/htdocs/] pass through D:/xampp/htdocs/kgpwed.html My problem is with the logic of '!-f' versus '-f' - my reading (and all examples I've found) suggest that '!-f' means 'the file DOES NOT exist' and '-f' means 'the file DOES exist' - but the actual operation (as shown in the traces) is the opposite behaviour.
