.NET Forum / ASP.NET / General / March 2008Redirect after 5 seconds only if bolNeedToRedirect=True ?
I want to redirect a vb.net aspx page after 5 seconds only if a variable bolNeedToRedirect=True. This variable is determined after code sees whether a person is logged in. How could I achive this considering the header meta tag for redirecting can't be switched based on a Boolean variable? Hello Jonathan, There are several ways to redirect the users to another page: Category A: redirect with html client side code: http://vancouver-webpages.com/META/FAQ.html#redirect A1. Location Http header A2. Refresh meta tag A3. <body onload="document.location='http://other.org/'"> e.g. <SCRIPT LANGUAGE="JavaScript"> redirTime = "2"; redirURL = "http://www.microsoft.com"; function redirTimer() { self.setTimeout("self.location.href = redirURL;",redirTime); } </script> <body onLoad="redirTimer()"> Category B: redirect with server side code: e.g Response.Redirect("Otherpage.aspx"); To accomplish task that the page is redirected after 5 seconds if the user logs in, we can do it in this way: protected void Page_Load(object sender, EventArgs e) { if ( // pass login check ) { Response.Write("<script>redirTimer();</script>"); // call the javascript to redirect the page // or Response.Redirect("Otherpage.aspx"); // redirect with server side code. } } Hope it helps.

I haven't tried it yet but: a) I don't want any JavaScript since some people might have it disabled b) Do you know what the VB.net code would be for the conditional timed redirect? I appreciate that you gave me C# but I have been programming in VB.net. TIA > Hi Jonathan, > [quoted text clipped - 17 lines] > This posting is provided "AS IS" with no warranties, and confers no rights. > ================================================= Hello Jonathan, "Delayed" page redirecting is a client side happening. Server side code is not able to control when to redirect the page directly. It needs to write some javascript code to client side, and let the client code finish the redirecting. The corresponding VB.NET code is: Response.Write("<script>redirTimer();</script>") (remove the ';' in the end of the C# code line) Regards, Jialiang Ge (jialge@online.microsoft.com, remove 'online.')
