Telnet is an old utility used in local network to offer a bidirectional communication text-oriented using a terminal. Can be used also to make an http call to a remote server with the purpose of testing. Let’s see how:
- Open you favorite terminal
Type (instead of diegor.it you can choose whatever server you want)
$ telnet diegor.it 80
and you should have as output:
Trying 18.104.22.168... Connected to diegor.it. Escape character is '^]'.
GET / HTTP/1.1 host: diegor.it
where “/” is the remote path. In this case we want the root. The output looks like this below:
HTTP/1.1 200 OK Date: Mon, 13 Jun 2011 09:06:43 GMT Server: Apache Cache-Control: no-cache, must-revalidate, max-age=0 Pragma: no-cache Expires: Wed, 11 Jan 1984 05:00:00 GMT Last-Modified: Sun, 12 Jun 2011 13:29:48 GMT Vary: Accept-Encoding Content-Length: 85589 Content-Type: text/html;charset=UTF-8 ...
Pretty simple! Any questions or comments are welcome.
