|

|
// Here's what we do, roughly in the order specified by HTML5:
|
|
// 1. Serialize aData using structured clone.
|
|
// 2. If the third argument is present,
|
|
// a. Resolve the url, relative to the first script's base URL
|
|
// b. If (a) fails, raise a SECURITY_ERR
|
|
// c. Compare the resulting absolute URL to the document's address. If
|
|
// any part of the URLs difer other than the <path>, <query>, and
|
|
// <fragment> components, raise a SECURITY_ERR and abort.
|
|
// 3. If !aReplace:
|
|
// Remove from the session history all entries after the current entry,
|
|
// as we would after a regular navigation, and save the current
|
|
// entry's scroll position (bug 590573).
|
|
// 4. As apropriate, either add a state object entry to the session history
|
|
// after the current entry with the following properties, or modify the
|
|
// current session history entry to set
|
|
// a. cloned data as the state object,
|
|
// b. if the third argument was present, the absolute URL found in
|
|
// step 2
|
|
// Also clear the new history entry's POST data (see bug 580069).
|
|
// 5. If aReplace is false (i.e. we're doing a pushState instead of a
|
|
// replaceState), notify bfcache that we've navigated to a new page.
|
|
// 6. If the third argument is present, set the document's current address
|
|
// to the absolute URL found in step 2.
|
|
//
|
|
// It's important that this function not run arbitrary scripts after step 1
|
|
// and before completing step 5. For example, if a script called
|
|
// history.back() before we completed step 5, bfcache might destroy an
|
|
// active content viewer. Since EvictOutOfRangeContentViewers at the end of
|
|
// step 5 might run script, we can't just put a script blocker around the
|
|
// critical section.
|
|
//
|
|
// Note that we completely ignore the aTitle parameter.
