Redirect from HTTP to HTTPS in ASP.NET

Tweet

Here’s a simple way to redirect a user from HTTP to HTTPS. I have tested a few scenarios with the code and it has worked fine. Let me know if you face any issues with the code

C#

protected void Page_Load(object sender, EventArgs e)
{
        if (!Request.IsSecureConnection)
        {           
            UriBuilder uri = new UriBuilder(Page.Request.Url);
            uri.Scheme = Uri.UriSchemeHttps;

            // Redirect to https
            Response.Redirect(uri.ToString());
        }
}

VB.NET

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
        If Not Request.IsSecureConnection Then
            Dim uri As New UriBuilder(Page.Request.Url)
            uri.Scheme = Uri.UriSchemeHttps

            ' Redirect to https
            Response.Redirect(uri.ToString())
        End If
End Sub

The IsSecureConnection property of the HttpRequest class gets a value indicating whether the HTTP connection uses secure sockets. Is not, the uri scheme is changed to https and the user is redirected
