Bug 72971 – Incorrect coalescing of session history entry after pushState'ing to URL with a 301 redirect

• Status: NEW
• Component: History

[Justin Lebar]

STR:

 * Visit http://people.mozilla.org/~jlebar/webkit/shentry-301/index.html
 * Click "go".  The link's onclick handler uses pushState to change the URI to 301.html.  The link's action (navigate to 301.html) is not canceled, so we navigate to 301.html.  But that's a redirect to 301-target.html.

Expected results:

Expect to have three session history entries (three entries when you click and hold the back button):

  * Original page (index.html)
  * 301.html (result of pushState)
  * 301-target.html (result of navigating to 301.html and then being redirected to 301-target.html)

Actual results:

Only two session history entries are created: index.html and 301-target.html.

Note that if we pushState to a different URI (that is, the target of the pushState is not the same as the target of the link), then we get three session history entries, as expected.

See https://bugzilla.mozilla.org/show_bug.cgi?id=701365 where we determined that this is your bug, not ours.  :)

History confuses me.

fishd, who should look at this bug?
