I am creating a WinForm app that will request page from a site that is of course protected by login name and password. I have no problem logging in but the login page creates several cookies and redirects to the member home page. During this redirect process the code doesn't stop so that I can collect the cookies for later responses (because the cookies have user info in them that identify your later requests). Is there anyway to deal with pages that do response.redirect and get the intermin page's response before the webrequest object goes on to the new page? I'm not using an asynchronous methods right now but was wondering if that could be a solution. I don't know if the async method would be called when the redirect is sent. Any ideas would sure be appreciated.
You cab use a CookieContainer to manage the cookies for your webrequest

C# Example
CookieContainer cookies = new CookieContainer();
cookies.Add(new Cookie("foo", "bar", "/", "www.tempuri.com"));
client.CookieContainer = cookies;

Yeah that works fine when there is no Response.Redirect from the server. When the the server sends a response.redirect the cookies don't get stored in the local CookieCollection. The do however get passed to the page that the redirect is pointed to.
In case you want to inspect the cookies of a redirect response you can try
to set the AllowAutoRedirect property to false
