| This test clicks a link that loads a URL into an iframe.<br> |
| The URL redirects to a different, random URL every time the link is clicked.<br> |
| When main resources are in the memory cache they are keyed off the original URL, not the post-redirect URL.<br> |
| In the case where the redirect takes us to a different URL than the CachedResource we're revalidating, we need to abort the revalidate and issue an unconditional request.<br> |
| <br> |
| This test makes sure that trying the random redirect multiple times results in at least one different load result.<br> |
| Since the nature of this test is "random redirects", it runs enough multiple iterations to make it very likely we'll get at least one different redirect.<br> |
