exclude a directory from rewrite

[simham_uk]

Hi all

I have a rule that rewrites all .html files to an index.php file, like so:

RewriteRule ^(.*)\.(html)$ index.php [L]

But what I'd like to do is exclude certain directories from being rewritten, such as:

/otherpages/*.html

Thanks in advace for you help.

RewriteCond %{REQUEST_FILE} !/otherpages/
RewriteRule ^(.*)\.(html)$ index.php [L]
