| <title>Test Caching "max-age" For History Only</title> |
| </head> |

| <p> |
| This test checks that loading a subresource with "Cache-Control: max-age=0" is |
| cached and reused in back navigation when the page is not in the page cache. |
| </p> |
| <p> |
| We then test that loading the same subresource is refetched when used in |
| non-stale loads such as refreshes or normal navigation. |
