WordPress MU

Hi all,

I'm just curious to understand what this bit in my htaccess actually does?


RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule . - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-.*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*.php)$ $2 [L]
RewriteRule . index.php [L]


:)

In a nutshell, it's verifying if the request is for a valid directory or file first, and if it is it passes through.

If not, it sends it to the appropriate MU file to translate the request into an MU generated page.

Didn't get that much more clever, but thanks :D
