measure the latency and throughput of a webserver

# man httping
       -b     Use this switch together with -G. When this option is used, the transferspeed (in KB/s) is shown.
       -G     Do a GET request instead of a HEAD request: this means that also the complete page/file  must  be  transferred.
              Note that in this case youre no longer measuring the latency!
       -c count
              How many probes to send before exiting.
       -l     Connect using SSL: for this to work you need to give a ’ https’ -url or a 443 portnumber.
       -s     When a successfull transaction was done, show the HTTP statuscode (200, 404, etc.).
