Question

I’m connecting to real-time data on a remote server as a client. I want to send the following to a server and keep the connection open. This is a ‘push’ protocol.

http://server.domain.com:80/protocol/dosomething.txt?POSTDATA=thePostData

I can call this in a browser and it’s fine. However, if I try to use telnet directly in a windows command prompt, the prompt just exits.

  GET protocol/dosomething.txt?POSTDATA=thePostData

The same is the case if I use Putty.exe and select Telnet as the protocol. I can’t see a way to do this with Hercules at all, as I don’t think the server will interpret the GET

Is there any way I can do this?

Thanks.

You have to match the HTTP protocol (RFC2616) to the letter if you want to use telnet. Try something like:

shell$ telnet www.google.com 80
Trying 173.194.43.50...
Connected to www.google.com (173.194.43.50).
Escape character is '^]'.
GET / HTTP/1.1
Host: www.google.com:80
Connection: close

HTTP/1.1 200 OK
Date: Tue, 11 Sep 2012 15:09:51 GMT
...

You need to type the following lines including an "empty line" following the "Connection" line.

GET / HTTP/1.1
Host: www.google.com:80
Connection: close
