    {

    //Redirect to Default page
    Response.Redirect("default.aspx");
    }

Problem

I want to implement forms based authentication manually in my website. I am using `Web.config` file for data store ``` <authentication mode="Forms"> <forms loginUrl="~/Login.aspx" name=".ASPXAUTH" path="/" requireSSL="false" slidingExpiration="true" defaultUrl="~/Admin/OrderHistory.aspx" cookieless="UseDeviceProfile" enableCrossAppRedirects="false" > <credentials passwordFormat="Clear"> <user name="Admin" password="adm123$"/> <user name="Administrator" password="adm234%"/> </credentials> </forms> </authentication> <authorization> <deny users ="?" /> <allow users = "*" /> </authorization> ``` There is a `Login.aspx` page at root level in that im using ASP.NET login control to get username and password. Everything works fine but when the user is `logged in` and manually go to `login.aspx` page, its not redirect the user to defaultUrl page. I want to redirect the user to a specific page/defaultUrl page, if he is logged in and came manually to login.aspx page How to do it? Login Button-Click ``` if (FormsAuthentication.Authenticate(LoginUser.UserName, LoginUser.Password)) { FormsAuthentication.RedirectFromLoginPage(LoginUser.UserName, true); } ```
