Re: SEARCH attack



OK, you've gone beyond me.  What do you mean by blocking the NOP operation
or jmp/mov instruction?  How would you do this with an Apache server on a
Linux platform?

Also, wouldn't replacing the www.microsoft.com with localhost (or
http://127.0.0.1/) just send the request right back to my own server,
probably even putting it in a loop?
