Hi Gurdip,

unless you're using HTTP/1.0 without keep-alive sessions, then it would be more effective to evaluate the Client IP during the CLIENT_ACCEPTED event (triggered once at the beginning of each TCP session), store the 

[class match]
results into a 
$variable
and the use the stored results on each single HTTP_REQUEST.

when CLIENT_ACCEPTED {
    if { [class match [IP::client_addr] equals my_ip_dg] } {
        set is_redirect 1
    } else {
        set is_redirect 0
    }
}
when HTTP_REQUEST {
    if { $is_redirect } then {
        if { [string tolower [HTTP::path]] equals "/somepath" } then {
            HTTP::redirect "http://10.200.200.200"
        }
    }
}

Note: Feel free to combinate the 

if $is_redirect
and 
if HTTP::path
conditions. I've splitted them just for demonstration purposes.

Cheers, Kai
