Hi all,

protected network ------E0(Router)ATM0/0/0-------PublicN/w (server)

Question:
Virus has identified to specific trigger like "*cmd.exe" . So, Stop
all the GET message for that .

Solution::
Class-map match-any blockvirus
      match protocol http url "*cmd.exe"
policy-map blockvirus
     class blockvirus
      police 8000 confirm drop exceed drop
inter ATM 0/0/0
   service-policy input blockvirus

My Questions:
Question Says GET Message should be blocked....But solution looks for
"*cmd.exe" in URL of response. (by the way of applying service
policy at input).

- Is the Solution Correct ? Suggestions/Alternatives ?
- Does that mean the HTTP reply have the "query" in it ?

Thanks
SAN
