title: Add second language support with root path in an existing ASP.NET WebForms site
body: <p>I have inherited from a very small ASP.NET WebForms project, and my customer would like to add a second language to it.</p>
  
  <p>For every "somepage.aspx", I'd like to support a "second language path" version of it, like "fr/somepage.aspx". I'd like to handle this using normal globalization (CurrentCulture + resource files in both languages) and avoid having to duplicate each page. I must keep the original paths valid, thus I have excluded ASP.NET MVC for now (for lack of knowing if I could continue to support ".aspx" paths).</p>
  
  <p>Is this possible?</p>
