[kentdeskman]

I have these code got errors
Code:

<IfModule mod_rewrite.c>
RewriteEngine on
^/(.*)\.SM([a-fA-F0-9]{32})\.swf$ /securemedia.php?file=$1&key=$2
</IfModule>

I think this to redirect all access to .swf file to /securemedia.php. Can someone check this for me .. I dont have any knowledge about .htaccess usage
