/**
|
|
* Bug 1300461 identifies that if a history entry was not bfcached, and
|
|
* a http redirection happens when navigating to that entry, the history
|
|
* index would mess up.
|
|
*
|
|
* The test case emulates the circumstance by the following steps
|
|
* 1) Navigate to file_bug1300461_back.html which is not bf-cachable.
|
|
* 2) In file_bug1300461_back.html, replace its own history state to
|
|
* file_bug1300461_redirect.html.
|
|
* 3) Back, and then forward. Since the document is not in bfcache, it
|
|
* tries to load file_bug1300461_redirect.html directly.
|
|
* 4) file_bug1300461_redirect.html redirects UA to
|
|
* file_bug1300461_back.html through HTTP 301 header.
|
|
*
|
|
* We verify the history index, canGoBack, canGoForward, etc. keep correct
|
|
* in this process.
