Change the attribute in Web config from util/login.aspx to your custom login page. Implement a check box for remember me that stores the cookie for authentication as permanent. It's a bool flag on the formsauthentication class that you should set to true if I remember correctly.

 [HttpPost]
public ActionResult Login(Models.User user)
{
if (ModelState.IsValid)
{
if (Membership.ValidateUser(user.UserName, user.Password))
{
FormsAuthentication.SetAuthCookie(user.UserName, user.RememberMe);
return RedirectToAction("Index");
}
else
{
ModelState.AddModelError(string.Empty, "Login failed!");
}
}
return View(user);
}

i am using FormsAuthentication in login post action.

Can you please explain your thought more briefly.

With that I think all you need is change login url in Web.config. Search for /util/login.aspx and replace with url to your login page. Episerver will take care of the rest for redirects...

Thanks a lot i got it working
