.htaccess: Multiple URLs catches filename

[rasmusbang]

Hi,

I have the following line in my .htaccess:
RewriteRule privacy stdpage.php?slug=privacy [L]

So if you go to the www.mysite.com/privacy it takes the stdpage.php with the argument above.

But if you go to www.mysite.com/privacysssssssss catches the same file.

How can I prevent this? It will give me multiple URLs with the exact same content. I have a 404 page which i would like to show instead when the match is not 100%.

And another question.

If i have a file named filename.php I can not make and use a css file named filename.css. The names clash in some way.
