What does the FormsAuthentication.SetAuthCookie() method do? RedirectFromLoginPage()?

Question

ICSM Computer · Answer

FormsAuthentication.SetAuthCookie(string userName, bool createPersistentCookie)
Creates an authentication cookie for the specified user.The cookie is added to the response, but no redirect happens.Use this when you want to manually handle the redirect after setting the cookie.You typically call this when you want more control over what happens next (e.g., redirecting to a custom page or doing some logic before redirect).
Example:
FormsAuthentication.SetAuthCookie(username, false);
// Now manually redirect wherever you want
Response.Redirect("Home.aspx");
FormsAuthentication.RedirectFromLoginPage(string userName, bool createPersistentCookie)
Creates the authentication cookie and immediately redirects the user.Redirects to the originally requested page (the URL the user initially tried to access before being redirected to the login page).This method combines setting the cookie and redirecting in one call, simplifying the login flow.
Example:
FormsAuthentication.RedirectFromLoginPage(username, false);
// Automatically redirects to original requested URL or default page
Summary:

Control Over Redirect
SetAuthCookie

No
None (you handle manually)
Full control after setting cookie
RedirectFromLoginPage

Use SetAuthCookie if you want to set the cookie but decide where and when to redirect yourself.Use RedirectFromLoginPage if you want to set the cookie and let ASP.NET redirect automatically to the page the user wanted originally.
