writing an irule to log all traffic

So something like this

when CLIENT_ACCEPTED {
 Get time for start of TCP connection in milleseconds
if { [HTTP::cookie exists "testcookie"]  } {
set tcp_start_time [clock clicks -milliseconds]
 
 Log the start of a new TCP connection
log "New TCP connection from [IP::client_addr]:[TCP::client_port] to [IP::local_addr]:[TCP::local_port]"
}
when HTTP_REQUEST {
 Get time for start of HTTP request
set http_request_time [clock clicks -milliseconds]
 
 Log the start of a new HTTP request
set LogString "Client [IP::client_addr]:[TCP::client_port] -> [HTTP::host][HTTP::uri]"
log local0. "$LogString (request)"
}
 
when HTTP_RESPONSE {
 Received the response headers from the server.  Log the pool name, IP and port, status and time delta
log local0. "$LogString (response) - pool info: [LB::server] - status: [HTTP::status] (request/response delta: [expr [clock clicks -milliseconds] - $http_request_time]ms)"
}
when CLIENT_CLOSED {
 Log the end time of the TCP connection
log "Closed TCP connection from [IP::client_addr]:[TCP::client_port] to [IP::local_addr]:[TCP::local_port] (open for: [expr [clock clicks -milliseconds] - $tcp_start_time]ms)"
}

Will this just log the requests that contain that cookie value and give the response times? and does this just write the info to the standard log file?

Thanks for your help
