Your code works fine for me.  You should consider setting up a server on 
your computer so that you can test your web programs.  Then you can 
write a simple cgi program to echo back some information, like the 
name/value pairs sent to the server in a query string(GET) or in the 
body of the request(POST).

If the first line of the response is "HTTP/1.1 200 OK" and there is no 
resp.content, then the server didn't send anything back to your program.

httpclient automatically handles cookies for you--you don't have to do 
anything.  httpclient sends back any cookies that were set by the server 
while your program is running.  If you want to save the cookies for the 
next time you run your program, that's when you use set_cookie_store() 
and save_cookie_store().

Also, you should not be using :follow_redirect with a POST request:

- (Object) post(uri, *args, &block)

Sends POST request to the specified URL. See request for arguments. You 
should not depend on :follow_redirect => true for POST method. It sends 
the same POST method to the new location which is prohibited in HTTP 
spec.
