Disable mod_rewrite for a specific folder

[giacomogd1]

Hi,
in my website each request is rewritten as follows:

RewriteRule ^/*([-a-zA-Z0-9_/]+)\.html$ /mainfile.php?request=$1

Now I have some stand-alone .html files I don't want to be catched by mod_rewrite. They are all in the /documents/ folder. How can I prevent mod_rewrite to catch 'em?

RewriteCond %{REQUEST_URI} !/file-you-dont-want-the-mod-for-1\.html$
RewriteCond %{REQUEST_URI} !/file-you-dont-want-the-mod-for-2\.html$
RewriteRule ^/*([-a-zA-Z0-9_/]+)\.html$ /mainfile.php?request=$1
