RequireSSL Attribute For ASP.NET

Here is a quick Custom Attribute in order to Define if a Page must be in HTTP SSL Mode and switch it to SSL if not.

[AttributeUsage(AttributeTargets.Class)]
public class RequireSSLAttribute : Attribute
{
 public static void Validate(IHttpHandler handler)
 {
     Type type = handler.GetType();
     Object[] objs = type.GetCustomAttributes(typeof(RequireSSLAttribute), true);
     if (objs != null && objs.Count() > 0)
     {
         SwitchToSsl();
     }
 }
 private static void SwitchToSsl()
 {
#if DEBUG
         return;
#endif
     String baseUrl = HttpContext.Current.Request.Url.OriginalString;
     Uri uri = new Uri(baseUrl);
     String url = baseUrl.Replace(uri.Scheme, Uri.UriSchemeHttps);
     HttpContext.Current.Response.Redirect(url, true);
 }
}

A Sample Page Implementation

In order to make it working, you just need to call RequireSSLAttribute Validate Method. On Page Constructor might be fine :)

[RequireSSL]
public partial class _Default : Page
{
 public _Default()
 {
     RequireSSLAttribute.Validate(this);
 }

 protected void Page_Load(object sender, EventArgs e)
 {
 }
}
