<body onload="test()">
<p>This test uses testRunner.overridePreference("WebKitUsesPageCachePreferenceKey", 1); to enable
back-forward WebKit page cache for the duration of the test.
The test enables cache, navigates to page-1, then to page-2 and then does history.back() to page-1.
On navigation back to page-1, test verifies that previously-initialized timer continues to fire and
onload is not called again.
If test fails it hangs or outputs 'FAIL' below.
