ASP .NET - Redirecting to HTTPS

On a project where I had to install a third party shopping cart, one issue that came up was to make sure all the pages ran under https (many hard coded links used "http").

I put the following code in the Global.asax file:

protected void Application_BeginRequest(Object sender, EventArgs e)
{
    if (Request.Url.Port != 443)
    {
        Response.Redirect ("https://www.yourdomain.com" +  Request.Url.AbsolutePath, true);
    }
}

This uses


Request.IsSecureConnection


to determine if the call was made over SSL.

So

if (Request.IsSecureConnection)
{
    Response.Write("HTTPS");
}
else
{
    Response.Write("HTTP");
}

Another way to write this:

if (!Request.IsSecureConnection)
{ 
    string serverName =HttpUtility.UrlEncode(Request.ServerVariables["SERVER_NAME"]);        
    string filePath = Request.FilePath;
    Response.Redirect("https://" + serverName + filePath);
}
