/*
|
|
* The test is designed to work with and without bfcache.
|
|
* (1) First the test opens a window which then loads another page which
|
|
* goes back to the original page to detect if bfcache is enabled. If
|
|
* bfcache isn't enabled, close message is sent to the opened window and it
|
|
* closes itself and sends a message back and the test finishes.
|
|
* (2) The browser is set to offline mode. The opened page sends message
|
|
* that it has received offline event. This controller page then asks the
|
|
* page to go forward. The page which comes out from the bfcache gets
|
|
* offline event and sends message about that to this controller.
|
|
* (3) Browser is set to online mode. Similar cycle as with offline happens.
|
|
* (4) Controller page sends close message to the opened window and it
|
|
* closes itself and sends a message back and the test finishes.
