title: Windows Phone Open .rails web page
body: <p>i'm developing a WP 8.1 app in C#, in one page i have to open a ".rail" web page (in webview) but every time i'll open that page the phone ask me to install an app from the store to satisfy the request.</p>
  
  <p>There's any way to prevent this behavior or there's something that i've misconfigured in webView?</p>
  
  <p>Thanks in advance</p>
