    Hi,

    What kind of virtual server do you want to use this for? Is it for a standard L7 "inbound" load balancing VS or an outbound proxy.

    If you want to drop, send a TCP reset or send an HTTP response when a client makes a request to a specific host and or URI for an inbound request, you can use an iRule like this: 

     
 when HTTP_REQUEST { 
  
     Check requested host header value 
    if {[string tolower [HTTP::host]] contains "tw.yahoo.com"}{ 
  
        Drop the connection 
       drop 
  
        Reset the connection 
       reject 
  
        Send a 403 response 
       HTTP::respond 403 Content {Not allowed} 
    } 
 }

    If you want to check the URI, you can use HTTP::uri to get the value.
