Development Tools HTTP Basics Introduction to HTTP Sending Data with a GET Request

Keep getting "command not found" when sending data with get request.

After following the example for sending data with a get request i keep running in the same problem.

telnet httpbin.org 80 GET /get?firstname=Chris&language=English HTTP /1.1 host:httpbin.org

However i get "command not found" or closed by foreign host. so i am totally stuck. any help would be great.

Connection closed is probably because you aren't typing it in fast enough. You probably only have 20-30 seconds to type in the GET /get ... before the connection is closed.

Where are you running telnet? If on your local computer, you might not have it installed. That is why it says "command not found".

If on the workspace, then you have to press "Enter" 2 times after typing "host: httpbin.org".

treehouse: ~/workspace$ telnet httpbin.org 80
Connected to httpbin.org.
Escape character is '^]'.
GET /get?firstname=John&language=English HTTP/1.1
host: httpbin.org

Hi there i am using the workspace but when i click the first time i get hosConnection closed by foreign host. so as you can see i dont get the chance to finnish the host:httpbin.org.

so when i try the other examples in course (the html and xml resource )every thing seems to work fine if i am quick but you have to be very quick. So i guess its only logical that i am connecting to the server ok. so i guess i'll have to type faster. Massive thankyou for your help.
