It should work... You do know that \r\n\r\n means two CRLFs tho?

Do this from the command prompt

telnet your_empeg_ip 80 <PRESS ENTER>
GET /proc/uptime HTTP/1.0<PRESS ENTER>
<PRESS ENTER>

You probably won't be able to see yourself typing GET /proc/uptime etc... but just do it blindly.

It should display some numbers and then close the connection.
