ip debug httpprobe
Send a HTTP probe.
This HTTP probe will measure the Round Trip Time (RTT) taken to connect and access data from a HTTP
server.
SYNTAX:
where:
EXAMPLE:
The first example shows the measured time for a file that was downloaded:
If the URL of a normal HTML page is used the figures are not so relevant, as shown in the example below:
DESCRIPTION:
>
RTT taken to perform domain name lookup.
>
RTT taken to perform a TCP connect to the HTTP Server.
>
RTT taken to send a request and get a response back from the HTTP Server (the probe retrieves the base
HTML page only as body, and does not request hyperlinks within this page).
The SpeedTouch will send the HTTP request, receive the reply, and report the RTT statistics (including the size
of the page returned).
