// IE doesn't add changes to the URI's hash into the history unless the hash

// value corresponds to an actual named anchor in the document. To get around
|

// this IE difference, we use a background IFrame to maintain a back-forward
|
||||
// history, by updating the IFrame's query string to correspond to the
|
||||
// value of the main browser location's hash value.
|
||||
//
|
||||
// E.g. if the value of the browser window's location changes to
|
||||
//
|
||||
// #action=someAction
|
||||
//
|
||||
// ... then we'd update the IFrame's source to:
|
||||
//
|
||||
// ?action=someAction
|
||||
//
|
||||
// This design leads to a somewhat complex state machine, which is
|
||||
// described below:
|
||||
//
|
||||
// s1: Stable state - neither the window's location has changed nor
|
||||
// has the IFrame's location. Note that this is the 99.9% case, so
|
||||
// we optimize for it.
|
||||
// Transitions: s1, s2, s3
|
||||
// s2: Window's location changed - when a user clicks a hyperlink or
|
||||
// code programmatically changes the window's URI.
|
||||
// Transitions: s4
|
||||
// s3: Iframe's location changed as a result of user pressing back or
|
||||
// forward - when the user presses back or forward, the location of
|
||||
// the background's iframe changes to the previous or next value in
|
||||
// its history.
|
||||
// Transitions: s1
|
||||
// s4: IEUriMonitor has programmatically changed the location of the
|
||||
// background iframe, but it's location hasn't yet changed. In this
|
||||
// case we do nothing because we need to wait for the iframe's
|
||||
// location to reflect its actual state.
|
||||
// Transitions: s4, s5
|
||||
// s5: IEUriMonitor has programmatically changed the location of the
|
||||
// background iframe, and the iframe's location has caught up with
|
||||
// reality. In this case we need to transition to s1.
|
||||
// Transitions: s1
|
