Home mod_rewrite rule to redirect all requests except for one specific path
 I'm trying to redirect all requests to my domain to another domain using mod_rewrite in an Apache 2.2 VirtualHost declaration. There is one exception to this -- I'd like all requests to the /audio path not to be redirected. I've written a RewriteCond and RewriteRule to do this but it's not quite right and I can't figure out why. The regular expression contains a negative lookahead for the string "/audio", but for some reason this isn't matching. Here's the definition: RewriteEngine on RewriteCond %{HTTP_HOST} ^(.*\.)?mydomain\.net(?!/audio) [NC] RewriteRule ^(.*)$http://www.newdomain.net [L,R=301]  If I change the RewriteCond to: RewriteCond %{HTTP_HOST} ^(.*\.)?mydomain\.net/(?!audio) [NC]  (i.e. put the forward slash outside of the negative lookahead part) then it works, but the downside of this is that requests to mydomain.net without a trailing slash will not be redirected. Can anyone point out what I'm doing wrong? (Note: the angle brackets around the domain in the RewriteRule bit above are being added by StackOverflow.com -- they are not there in the actual code!) Here are the rules:  ServerAdmin me@mydomain.net DocumentRoot "/var/www/mydomain.net/htdocs" ServerName www.mydomain.net ServerAlias mydomain.net RewriteEngine on RewriteCond {REQUEST_URI} !^/audio RewriteRule ^(.*)$ http://www.newdomain.net [L,R=301] RewriteLog logs/mod_rewrite_log RewriteLogLevel 3 ErrorLog logs/error_log CustomLog logs/access_log common  Thanks @mercutio -- that makes perfect sense but it still doesn't seem to work. Here's what the mod_rewrite log says when I make a request to http://mydomain.net/audio/something.mp3: (2) init rewrite engine with requested uri /audio/something.mp3 (3) applying pattern '^(.*)\$' to uri '/audio' (2) rewrite '/audio' -> 'http://www.newdomain.net/' (2) explicitly forcing redirect with http://www.newdomain.net (1) escaping http://www.newdomain.net for redirect (1) redirect to http://www.newdomain.net [REDIRECT/301]  Since the REQUEST_URI does start with /audio I would expect the RewriteRule to be ignored.
