Programs: Lock up your servers against Fusker

[cd34]

This rule allows empty referrers:

RewriteCond %{HTTP_REFERER} !^$ [NC]

GrandmaScrotum, phew, that ruleset has been floating around the net for a long time, and, its got many common errors. First, there is a space missing before the P, so, it would never match this. The non-anchored match at the front and the floating match to end of string aren't needed either.

RewriteCond %{HTTP_USER_AGENT} ^.*DISCo\Pump.*$ [OR]

Would be better as:

RewriteCond %{HTTP_USER_AGENT} ^DISCo\ Pump [OR]

and I sort of changed these by putting:

RewriteCond %{HTTP_USER_AGENT} ^Mozilla
RewriteRule /* - [L]

In front of your list of rules.

However, I really question whether those rules really do much anymore, since many surfers pretend to be Mozilla anyway.

But, if you were going to do it:
