.htaccess rule not excluding existing files when rule has a slash condition - .htaccess

Question

I am redirecting this type of url
http://www.site.com/windows/games/ or http://www.site.com/windows/games
http://www.site.com/windows/software/ or http://www.site.com/windows/software
to
http://www.site.com/windows/ct.php?ct=games
http://www.site.com/windows/ct.php?ct=software
Site structure
wamp/www/Site/windows/ct.php
I am trying this way its redirecting properly but when url has trailing slash at end its rewriting css, js files too.
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^windows/([^/]*)/?$ /Site/windows/ct.php?ct=$1 [L]
i.e
this type of url has css and javascript applied.
http://www.site.com/windows/games
but this type of url has no css and javascript applied. (not working with trailing slash).
http://www.site.com/windows/games/
I have tried several syntax like
RewriteRule ^windows/([^/]+)/?$ /windows/ct.php?ct=$1 [L]
RewriteRule ^windows/(^(.[^/]*)/?)$ /windows/ct.php?ct=$1 [L]
RewriteRule ^windows/([^/]*)/? /windows/ct.php?ct=$1 [L]
RewriteRule ^windows/([^/]+)/? /windows/ct.php?ct=$1 [L]
but it didn't work.
Complete .htaccess
Options +FollowSymlinks -MultiViews
RewriteEngine on
<IfModule mod_rewrite.c>
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^windows/([^/]*)/?$ /Site/windows/ct.php?ct=$1 [L]
RewriteRule ^[^/]*/[^/]*/(.*\.html) /Site/error/400/ [L]
RewriteRule ^(error) - [L]
RewriteRule ^sitemap\.xml$ sitemap.php [L]
RewriteRule ^rss/(.*?)\.xml$ rss/$1.php [L]
</IfModule>
ErrorDocument 404 /Site/error/404/
Please see and suggest any possible way to do it.
Thanks.

Answer 1

The issue here is that your relative paths break when you add a trailing slash as it introduces two-levels of directory structure while the CSS/JS file paths come out only once ... So, your RewriteRule is actually firing for CSS/JS files as well when resolving 404s for paths like /windows/global/js/js.js. But, the scripts still fail to work because they aren't under /Site and that's where your rule is serving the request from.
So, to fix things without touching the relative URLs or resource locations; add another rule as follows:
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^windows/([^/]*)/?$ /Site/windows/ct.php?ct=$1 [L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^windows/(global/.*)$ /$1 [L] # handles css|js files
The rest of your .htaccess (of course) remains the same.

I use the following rule in .htaccess, but this may be too general:
RewriteRule ^q/([^/]+)/([^/]+)(\/?)$ /path/to/q.php?type=$1&q=$2&{QUERY_STRING} [NC]
This may be better for you:
RewriteRule ^windows(\/?)$ /path/to/windows.php?{QUERY_STRING} [NC]
RewriteRule ^windows/([^/]+)(\/?)$ /path/to/windows.php?type=$1&{QUERY_STRING} [NC]
You will have to change this according to your situation. I haven't tested this, but I hope it is good enough for you to get where you want.
