title: 307 Redirect when loading analytics.js in Chrome
body: <p>I'm building a web app and using Google Analytics (analytics.js) for analytics.   I recently noticed that analytics aren't working properly in Chrome.</p>
  
  <p>I'm loading analytics using the standard code snippet in a separate module and included via requirejs.  I've verified that this script runs as expected and executes the analytics snippet.</p>
  
  <p>When I inspect network traffic in Firefox, I can see that the analytics script is loaded from Google as expected (HTTP 200 response):</p>

  <p>However, when I run the exact same page in Chrome, I get an HTTP 307 response pointing to about:blank, and analytics does not run:</p>

  <p>However, if I paste the analytics URL directly into the Chrome address bar, the script is found.  Any ideas what's going on here, or how to fix it?</p>
