If you know the files are in a specific location—such as right at the first path of the URL—then use something like LocationMatch
:
<IfModule mod_security2.c>
<LocationMatch /(mobile-bridge.php|bridge.php)>
SecRuleEngine Off
</LocationMatch>
</IfModule>
But there is a nice equivalent of that for files called FilesMatch
that should work as well:
<IfModule mod_security2.c>
<FilesMatch (mobile-bridge.php|bridge.php)>
SecRuleEngine Off
</FilesMatch >
</IfModule>
Or perhaps it would work like this:
<IfModule mod_security2.c>
<FilesMatch "([a-z],-)*bridge\.php$">
SecRuleEngine Off
</FilesMatch >
</IfModule>
