How to use EnableSession?

I designed a WEB SERVICE and called it through WINFORM. In the WEB METHOD, ENABLESESSION is set to TRUE. There is no problem in the browser debugging through the WEB SERVIE, but it is always unsuccessful when called through WINFORM.

The winform client must execute the following code:
  ser1 = New localhost.Service1'This is a web service object
  ser1.CookieContainer = New System.Net.CookieContainer'This is very important
In this way, the session use on the server side is no problem, IIS default session expiration time is 20 minutes.
