Also, please don't tell me to use Mechanize. I'm trying to improve the
documentation of this library.

Code ------------------
        domain = 'login.domain.com'
        script = '/login.cfm'
        params = 'emai@mail.com&password=passw4rd'
        Net::HTTP.start(domain,80){|http|
                loginRsp = http.post2(script,params)
                loginRsp.each {|key, val| puts key + ' = ' + val}
        puts "FIRST RESPONSE===========\r"
                puts loginRsp['location'] #Seems ok => Login2.domain.com
                request = Net::HTTP::Get.new(loginRsp['location'])
                headers = {'Cookie' => loginRsp.response['set-cookie']}
                firstRsp = http.request(request,headers)
        puts "SECOND RESPONSE===========\r"
                puts firstRsp['location']  #Might be ok. =>
Login.domain.com
                request = Net::HTTP::Get.new(firstRsp['location'])
                headers = {'Cookie' => firstRsp.response['set-cookie']}
                secondRsp = http.request(request,headers)
        puts "THIRD RESPONSE===========\r"
                puts secondRsp['location']  #Not right. Should be
home.domain.com but it is simply domain.com.
                request = Net::HTTP::Get.new(secondRsp['location'])
                headers = {'Cookie' => secondRsp.response['set-cookie']}
                thirdRsp = http.request(request,headers)
                puts "=======================END\r"
        }

Second, you keep reassigning your headers hash.  This means that even if
you were sending back a properly formatted cookie header, you would only
be sending back the last cookie you received!  The server could be
trying to set multiple cookies on your client, and expects that all of
those cookies be sent back.

Hope the helps!
