Quick ISAPI rewrite question.

This is actually a question I posted on the helicon forum, but I was wondering if anyone could answer it here? It involves a couple of rules for ISAPI rewrite.

Heres the rules:

This one just sticks index.php in front of ALL my urls:

RewriteRule ^(.*)$ index.php/$1 [L,QSA]

and the next one is an attempt to fix the above one, where the url starts with ‘wp-content/’, this is because the wp-content folder contains CSS/images and they are being broken by the first rule.

RewriteRule ^wp-content/(.*)$ /wp-content/$1

This rule doesn’t work, so to summarize, what I need to do is this:

stick index.php in front of all urls EXCEPT where they start ‘wp-content’.

Any ideas?

Many thanks
