I need to make an httpwebrequest in a winform.
The first call is ok, and it is in GET.
The second must use the cookie of the first call and then POST data to
a uri.

The are some sample code for manage cookies?

Check out the code snippets at
<URL:http://dotnet.mvps.org/dotnet/code/net/#CookieRequest> which
demonstrate two different ways of handling cookies in .NET.
