Description
When ICEmobile-SX/BridgeIt returns control to the browser, the URL fragment previously in place must be restored. For instance, if the user is on the page
http://host.com/myapp.html#camera
the same URL (including #camera) must be set.
http://host.com/myapp.html#camera
the same URL (including #camera) must be set.

Implementation for Android is simply to extract "h" from the parameters, store it, and echo back as "!h" if set.

As an intermediate implementation choice, the previous hash fragment was to be appended to #icemobilesx as #icemobilesx_encodedfragment_, however this still required changes to the ICEmobile-SX app, so an explicit parameter is being used instead.
This would have required escaping underscores within the encoded fragment as follows:
function underscoreEscape(str)
{ str = escape(str); str = str.replace(/_/g, '%5F'); return str; }

Fragment is restored, however the application developer must be aware that BridgeIt commands are recorded in the browser history and can be replayed with JavaScript history APIs.

The difficulty arises because ICEmobile-SX also uses the #fragment for returning values to the browser. This is implemented by passing a parameter "h" containing the hash fragment to be restored to ICEmobile-SX and having ICEmobile-SX echo this parameter in the URL response as a value for "!h".
