How to redirect everything via Web.config or C # to https: // www. site version?

I have an ASP.NET site hosted on GoDaddy. I need to redirect (301) each request https://www.example.com/whatever

So for example:

This is a piece of cake on Linux or cPanel hosting. But I don’t know how to do it on GoDaddy (I asked for support, but they seem to know nothing ...). I think this is easy to do with IIS, but GoDaddy does not give you access to IIS.

So, is there a way to do this through Web.config or C #? Preferably web.config

Check out this article, which contains several different options for preventing duplicate URLs on your ASP.NET site: Methods for preventing duplicate URLs in your Site . I have summarized the various methods below, but will review an article for more in-depth treatment, as well as a demo of ASP.NET.

Issuing persistent redirects from ASP.NET

You can check the incoming URL for each request in the event handler Global.asax Application_BeginRequest. If the URL is missing a host www., you can add it and make a permanent redirect to the new URL.

protected void Application_BeginRequest(object sender, EventArgs e)
{
   if (Request.Url.Authority.StartsWith("www"))
      return;

   var url = string.Format("{0}://www.{1}{2}",
               Request.Url.Scheme,
               Request.Url.Authority,
               Request.Url.PathAndQuery);

   Response.RedirectPermanent(url, true);
}

                  <add input="{HTTP_HOST}" pattern="^yoursite\.com$" />
               </conditions>

               <action type="Redirect" url="http://www.yoursite.com/{R:1}" redirectType="Permanent" />
            </rule>
         </rules>
      </rewrite>
