First with mod_access (as it is in 2.0) <Location /_vti_bin/_vti_aut/author.exe> Deny from all </Location> .. or fancier .. <LocationMatch ^/_vti_bin/_vti_(evil|regex)> Deny from all </LocationMatch> Or with mod_rewrite: RewriteEngine On RewriteCond %{REMOTE_ADDR} !^trusted.host.pattern$ RewriteRule ^/_vti - [F] This basically says, if the address looks like some frontpage nonsense and the client isn't coming from a known address, don't change the URL (the - part), and forbid [F] the request. You can probably get fancier still with mod_security, where fancy includes stuff like time based abuse escallation, and just about any conceivable formula based on the request (including any entity bodies, which mod_rewrite can't see). Good luck. -- noodl
Noodl, I tried the mod_rewrite suggestion which was working until I discovered it was killing the FP counter. So, switched to this as a separate rewrite block by itself since I send the mass downloaders to a special page explainy why blocked:
RewriteCond %{REMOTE_ADDR} !^xx.xx.xx.xx$
RewriteCond %{HTTP_USER_AGENT} FrontPage [NC,OR]
RewriteCond %{HTTP_USER_AGENT} MSFrontPage [NC]
RewriteRule ^.* - [F,L]
I think this is doing the trick now.
Many thanks!
Jack
