.htaccess mod_rewrite rules conflicting - regex

Question

I have the following rewrite rules:
Options +FollowSymLinks
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !\.(css|gif|ico|jpg|js|png|swf|txt)$
RewriteCond %{REQUEST_URI} !^/(Account|Logout|Password|Tags) [NC]
RewriteRule ^([^/]*)$ /index.php?city=$1 [QSA,L]
RewriteCond %{REQUEST_URI} ^/Account [NC]
RewriteRule ^Account /members/account.php [NC,L]
RewriteCond %{REQUEST_URI} ^/Logout [NC]
RewriteRule ^Logout /members/logout.php [NC,L]
RewriteCond %{REQUEST_URI} ^/Password [NC]
RewriteRule ^Password /members/password.php [NC,L]
RewriteCond %{REQUEST_URI} ^/Tags [NC]
RewriteRule ^Tags /members/tags.php [NC,L]
I'm trying to add another condition that so that it loads as
domain.com/$city/$provider/$name
this is the rule:
RewriteRule ^([^/]*)/([^/]*)/([^/]*)$ /listing.php?city=$1&provider=$2&urlname=$3 [L]
My issue is that this rule conflicts with the rule for my index file which loads as domain.com/$city.
I'd greatly appreciate any and all suggestions.
Thanks!

Answer 1

There's nothing wrong with any of your rules. Its just that the first covers the last in terms of what it will accept. The easiest way to avoid this problem is to move the more restrictive rule above of the more general. I.e. in this case put the Listing rule immediately before the index.php rule.
Addendum
Oops, The ->listing.php followed by the ->indexp.php rules will still loop because rule1 fires on the first pass and then rule2 on the second, since the query string is stripped for purposes of regexp matching in a rule; and "listing.php matches ^([^/]*)$.
You should only match ^([^/]*)$ in the case where the pattern doesn't match an existing file. The way to prevent this is to put a
RewriteCond %{REQUEST_FILENAME} !-f
before the index.php rule.
