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

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