Description David Levin 2009-08-20 23:02:31 PDT

Following the steps in https://bugs.webkit.org/show_bug.cgi?id=25399 (perhaps see the radar bugs), the ASSERT(!resource->m_proxyResource); in
CachedResource::setResourceToRevalidate may fire after using the lexisnexis site for some time.

(Using some notes from ap)
It seems to be due to a complicated combination of several frames including the
same script, and being reloaded using different navigation types at the same
time (like POST+reload or something) but an exact cause/repro hasn't been
determined yet.

Since there is logic that's supposed to prevent this sort of thing - preloaded
resources shouldn't be revalidated  for normal loads - it's not good that it
breaks on lexisnexis.

Also seeing this assertion loading a web archive of http://www.childrenscancer.org/zach/

This ASSERT reproduces for me running LayoutTests/cache/x-frame-options-304.html in a debug build in WebKit2 mode (while running the full test suite):

run-webkit-tests -2 --debug --batch-size=100000000 --iterations=8
