FormsAuthentication - can't get persistent cookie

[tcstom]

I just can't get my head round persistent cookies when using FormsAuthentication so I hope someone can help. Basically I have a login screen, and I want to create a persistent cookie which holds a few properties of the user, specifically their name, userID and access level. It doesn't matter what I do, my cookies always expire at session end. For example, after authenticating the login I'm using the following code...

Response.Redirect(FormsAuthentication.GetRedirectUrl(txtUser.Text, true));

This should create a persistent cookie. But if I close the browser and re-open it then Context.Request.IsAuthenticated returns false. How can I make a login persiste across sessions? What I'm looking for is direction to a decent tutorial to explain all this stuff, because I can find endless tutorials about the simple authentication and redirection process with FormsAuthentication, but nothing about how to maintain a persistent cookie or add information to the cookie that is created with the GetRedirectUrl method.

Any advice is appreciated.

Did you check your web.config?

The relevant lines in my web.config are:

<authentication mode="Forms">
  <forms name="XXXXXX_user" loginUrl="login.aspx" protection="All" timeout="30" path="/" />
</authentication>

My user accounts are in a database. I've tried without the timeout property, but my understanding is that persistent cookies ignore this anyway...

Try just using FormsAuthentication.RedirectFromLoginPage(username,true)and see if this will work for you. Everything else looks fine to me.

OK, will do. Will have to wait until I get home from work. Meanwhile, if this succeeds in creating a persistent cookie then will I be able to access it from the Response.Cookies collection as normal?

Yes you can access this from Response.cookies["cookieName"]
