How to force a page to use SSL (HTTPS)

The following sample code will force pages to use SSL (https) with ASP.NET 2.0:

//this is the current url 

System.Uri currentUrl = System.Web.HttpContext.Current.Request.Url;

//don't redirect if this is localhost

if (!currentUrl.IsLoopback)

{

    if (!currentUrl.Scheme.Equals(Uri.UriSchemeHttps, StringComparison.CurrentCultureIgnoreCase))

    {

        //build the secure uri

        System.UriBuilder secureUrlBuilder = new UriBuilder(currentUrl);

        secureUrlBuilder.Scheme = Uri.UriSchemeHttps;

        //use the default port. 

        secureUrlBuilder.Port = -1;

        //redirect and end the response.

        System.Web.HttpContext.Current.Response.Redirect(secureUrlBuilder.Uri.ToString());

    }

}

Hope it helps.
