How to login to a ASP.NET webpage automatically

Hi MYTAIR,
>>..How can I get the page to login automatically when a user visits the page witout redirecting to login.aspx?
You need to put one login page for Form authentication in web.config if the user not yet login through the system.
But, you may put some logic to bypass the login page that defined under other page that trying to invoke the page that need authentication.
eg:
                  //... server code that calling page that need authentication(eg: MemberTransactions.aspx), probably onClick event. You can apply it into your exact scenarios
                  FormsAuthentication.SetAuthCookie(YOURADUsername, false) ;
                  Response.Redirect("MemberTransactions.aspx", false);

Check this for further details:

Hi x com,
I've tried your solution:

FormsAuthentication.SetAuthCookie(YOURADUsername, false) ;
Response.Redirect("MemberTransactions.aspx", false);

but it just redirects me to the login page. It appears the cookie is not being set in my session.

Hi MYTAIR,
You can create the persist cookies there as described in the proposed MSDN site.
Response.Redirect("MemberTransactions.aspx", true);

Try delete the internet cache file and run the application again.
Lastly, post the code snippet here if the application still pointing to login page.

Hi x com,
I've tried it again. See code snippet below.

It causes a redirect to itself, which will never end. That is when it redirects to CWP_Default.aspx, it finds out the user is not logged in, and redirects back to CWPLogin.aspx.

CWPLogin.aspx
 
<script runat="server">
protected override void OnPreInit(EventArgs e)
    {
        base.OnPreInit(e);
             
        string username = "72315"; 
        
        FormsAuthentication.SetAuthCookie(username, true);
        
          
        Response.Redirect("http://dk-ta-cphrm2/CWP_WA/CWP_Default.aspx", true);
 
}

Hi MYTAIR,
Sorry for the delay reply. May i see the code that resides inside CWP_Default.aspx? Could be some logic is causing the page redirection to Login page?

Hi x com,
I wish I could, but I don't have access to the source code behind Login.aspx, because it's in a compiled dll.
