URL Blocking Question

Hi,

In my live traffic view, I see attempts to access the following non-existent URLs:

http://mywebsite/themes/cooltheme//lib/scripts/dl-skin.php

and

http://mywebsite/themes/whatevertheme//lib/scripts/dl-skin.php

Hoping to immediately block IP addresses related to attempts like these, I put:

/lib/scripts/dl-skin.php

in the box labeled “Immediately block IP’s that access these URLs”

Looking at the live traffic, this doesn’t seem to work. I see repeated attempts by the same IP address to access non-existent URLs ending in: /lib/scripts/dl-skin.php

Am I doing something wrong? If so, could someone please provide the correct syntax for this option?

Thanks!
