Redirect to SSL

Often times we come across need to redirect (enforcing) a request to SSL. To show how to do that server side, I wrote this blog a while ago and being a popular post, I'm writing a clean code that might help lot of my readers.

First, let's write a utility class that returns whether the request is SSL or not:

/// <summary>
/// Gets if the url is secure or not
/// </summary>
public static bool isSecureURL
{
    get
    {
        // Check the request
        if (HttpContext.Current.Request.IsSecureConnection ||
            (HttpContext.Current.Request.ServerVariables["HTTPS"] != null &&
            HttpContext.Current.Request.ServerVariables["HTTPS"].ToLower() == "on"))
            return true;
        if ((!string.IsNullOrEmpty(HttpContext.Current.Request.ServerVariables["HTTP_HOST"].ToString())) &&
            (HttpContext.Current.Request.ServerVariables["HTTP_HOST"].ToString().EndsWith("443")))
            return true;
        // url is not secure:
        return false;
    }
}

Notice that I use 2 condition checks. The first might work for some users but for others who go through proxy with no forwarding information, I'm trying to see if proxy is forwarding HTTP_HOST ending with SSL port (I use 443).

And now, to implement use something like this:

if (//My Condition to see whether I should implement SSL or not)
{
    if (!Utility.isSecureURL)
        Response.Redirect(Request.Url.ToString().Replace("http://", "https://"));
}

Love coding!
