asp.net mvc - MVC RequireHttps entire site -

I've read past posts about using RequireHttpsAttribute to protect different controllers:

But is there a way to apply it to the entire site? Due to my host (discountasp.net) I can not use the "RequireSSL IIS" setting.

Register Requirements HttpsAttribute as global filter.

in global.asax:

  protected zero application_Start () {GlobalFilters.Filters.Add (New RequireHttpsAttribute ()); // ... other stuff}
