   9     // cacheable sync XHR request.  Upon returning to that page, we expect the
  10     // sync XHR request to still succeed.  This relies on it loading from the
  11     // network and not being restricted to loading from the cache (as the main
  12     // page is).

  22 This test verifies that a synchronous XMLHttpRequest, generated from a page
  23 that is the result of a form submission, loads properly when the user navigates
  24 back to the page.
  25 <p>
  26 When navigating back to a page that resulted from a form submission, the page
  27 is loaded with the ReturnCacheDataDontLoad cache policy.  It is important that
  28 subresources (including XMLHttpRequest instances) do not inherit this cache
  29 policy.
