Using telnet to Simulate a HTTP Client

Internal

• HTTP

Overview

To close connection immediately:

telnet localhost 10000
GET /index.html HTTP/1.1
Host: localhost:10000
Connection: close

HTTP/1.1 200 OK
Content-Length: 37
Server: NovaOrdis http-server
Connection: close
...
Connection closed by foreign host.

To keep the connection alive (with httpd as proxy), instead of "Connection: close" send:

Connection: Keep-Alive

httpd will react to that if KeepAlive is "On", and will keep the connection alive for KeepAliveTimeout seconds.
