You mentioned mod_security. That to me seems the best candidate to block these types of requests. Mod Security has an extensive ruleset and I am certain it will have a way to accomplish this. Unfortunately, I am pretty much a novice as it comes to mod_security myself so I am unable to give you the syntax for such a rule from the top of my head. What I suggest is that you drop your inquiry on the mod_security mailinglist. R __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
