How to make an exception in mod_rewrite?

Question

Apache HTTP Server

I have the following instruction in .htaccess: Simply put, I direct all site.com/sometext requests to site.com/page.php?s=sometext But if I have a directory called "sometext" in the root of the site, then the redirect will work on a crooked url: site.com/sometext/?s=sometext How can I write exceptions for one or two directories?
RewriteRule ^([A-Za-z0-9-]+)$ page.php?s=$1 [PT]

Answer 1

The line below is inserted before the RewriteRule and allows you not to process the address value starting with /res/
You can write the second directory in the same form below, and so for all exception options, or tie regexps.

Answer 2

RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([A-Za-z0-9-]+)$ page.php?s=$1 [PT]
