title: When was S.browser_fallback_url introduced in Chrome?
body: <p>I'm writing a web application (JavaScript, angularJS, etc) that runs better on Chrome, so it tries to launch it when, it's running on Android and it's opened on the default Android Browser. 
  If Chrome isn't installed, I want it to go back to the Android Browser (instead of the Google Play store).</p>
  
  <p>So I'm using an intent of this form:
  intent://localhost:3011/#Intent;scheme=http;package=com.android.chrome;S.browser_fallback_url=<a href="http://localhost:3011/?intent=no;end" rel="nofollow">http://localhost:3011/?intent=no;end</a></p>
  
  <p>My problem is that when I run this on my android tablet (no-name, Lollipop 5.1.1, Default browser: Chrome 39) it doesn't work. When I use the separately installed Chrome (trying to load, e.g. firefox which isn't installed) it works.</p>
  
  <p>So in order to proceed I need to know if I'm doing something wrong, or if there's some other reason.
  My question really boils down to this: should the browser_fallback_url work in the old default browser, or is it a newer feature in Chrome (so it's useless to my use-case).</p>
  
  <p>Thanks.</p>
