How to test servlet using Telnet

Essentially what I need to do is just make an HTTP Call using Telnet.

$> telnet 127.0.0.1 9086

Ok, I'm connected, and now what??
I know which servlet I want to test, I know which parameters is expecting, then "let's do it":

Which method should I use? POST or GET?? let's use POST (due to well known limitations with GET)

This is my URL:

/MyWebApp/proxyServlet?operation=doSomethingNice&consumerName=myActiveMQConsumers&server=192.168.5.122:9080&targetServlet=/MyOtherWebApp/utilsServlet

I'll finish my command with the HTTP version I want to use: HTTP/1.0 (if I use 1.1 it'll keep you connected)

And finally let's put all together:
POST /MyWebApp/proxyServlet?operation=doSomethingNice&consumerName=myActiveMQConsumers&server=192.168.5.122:9080&targetServlet=/MyOtherWebApp/utilsServlet HTTP/1.0
Important: Once you have copied this full line in your telnet body, please type ENTER twice.

How do I know if this works? You should see this on your telnet console:

HTTP/1.0 200 OK
Content-Type: text/xml;charset=ISO-8859-1
Cache-Control: no-cache
Content-Language: en-US
Content-Length: 21
Date: Thu, 19 Aug 2010 18:38:45 GMT
Server: WebSphere Application Server/6.1

true

Connection to host lost.
