Development Tools HTTP Basics Introduction to HTTP HTTP Requests Using Telnet

Why am I getting no response from my requests submitted to httpbin.org?

I open the workspace and click in front of treehouse:~/workspace$ to place my cursor.

I type "telnet httpbin.org 80" and receive "Trying 54.236.246.173... Connected to httpbin.org. Escape character is '^]'."

I type either "GET / HTTP/1.1" or "GET /xml HTTP/1.1" and press enter to move my cursor to the next line.

I quickly type "Host: httpbin.org" and press enter expecting my screen to behave as Chris's does, but it moves my cursor to the next line, pauses briefly, and the displays "Connection closed by foreign host."

Am I doing something incorrectly or is there some other obstacle preventing my Workspace from operating as Chris's telnet request does?

Hi Benjamin Masterman

There are a couple things to note here. First is that Telenet times out very quickly (~ 10 seconds), which is why he says "quickly type".

Second, you state that you hit enter after Host: httpbin.org and nothing happens, but his instructions say to hit enter twice.

Give that a try.

:) :dizzy:

Thanks Jason! You nailed it. I had assumed when he said press enter twice that he was including a reference to clicking enter from the line above. Clicking enter once drops my cursor to the next line, and pressing it once more on an empty line seems to be the key to actually sending the request. :D
