+ /**
+ * 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.
