C# Application CookieContainer

Wondering if anyone had problems with the CookieContainer s, I was making a program that logs onto sites, check for news and then reports back.

All cookies domain in response.cookie s is marked as site.com except for one that is marked as .site.com for some reason this doesn't make it back to http://site.com when I try to check the messages page after doing the login.

If I override the WebResponse in WebClient and add a copy of that cookie without the initial dot all is well and I get my result. However this is not nice as I get extra cookies so I was wondering if anyone knew why?

To explain further:

public class WebClientEx : WebClient
	{
		private CookieContainer cookies = new CookieContainer();

		protected override WebRequest GetWebRequest(Uri address)
		{
			WebRequest retVal = base.GetWebRequest(address);

			if (retVal.GetType() == typeof(HttpWebRequest))
			{
				((HttpWebRequest)retVal).CookieContainer = cookies;
			}

			return retVal;
		}

		protected override WebResponse GetWebResponse(WebRequest request)
		{
			WebResponse retVal = base.GetWebResponse(request);

			if (retVal.GetType() == typeof(HttpWebResponse))
			{
				foreach (Cookie c in ((HttpWebResponse)retVal).Cookies)
				{
					if (c.Domain.StartsWith("."))
					{
						c.Domain = c.Domain.Substring(1);
						cookies.Add(c);
					}
				}
			}

			return retVal;
		}
	}

Not sure why the stuff in GetWebResponse has to be done but without it it doesn't work to login on some sites. So I am curious if someone knows what is different in WebClient from a Browser regarding cookie handling.
