Applying Rewrite Rules to root only.

I don't want my doc root rewrite rule to affect sub-directories

[erikcw]

I have a ReWrite rule (RewriteRule (.*)\.html$ $1.php) at document root, but I don't want this rule to apply to a sub-directory which is full of .html files (else it returns a 404 error). Any ideas?

Tell it that no more "/" characters are permitted ahead of ".html":

RewriteRule ^([^/]*)\.html$ $1.php
