There are many comments as well as open tickets about loading URLs =
within an application (at least for iOS).  I thought it might be =
worthwhile to compose a list of use cases in order to better understand =
which ones we can and want to support:

1) Entire app loaded from assets within www directory of the device.
2) Initial load via www/index.html then redirect to a Web URL or update =
assets via Web URL.
3) Application loads from a Web URL - no assets stored or updated on the =
device.
4) Application loads from a Web URL - some assets may be stored  or =
updated on the device.
5) Application displays ChildBrowser to load additional Web URLs=20
6) Application displays ChildBrowser to load Web URLs - wants to execute =
PhoneGap commands from within ChildBrowser
7) Application loads additional Web URLs via iFrame and wants user to =
navigate within iframe assets
8) Application loads additional Web URL via iFrame and wants to execute =
PhoneGap commands from within iFrame.

I don't think it matters where URLs are opened via xmlHttpRequest, links =
or scripting but maybe I am being naive?

I'm sure there are more, please add to the list.

As far as support in iOS here is my current understanding:

1) supported
2, 3,4) For 3,4 developer needs to make changes to native code (due to =
issue270).   Support depends on the type of redirection see =
https://github.com/phonegap/phonegap-iphone/issues/270
5) supported - have to deal with whitelist
6) not currently supported
7) broken see https://github.com/phonegap/phonegap-iphone/issues/296 =
(although that ticket is closed any redirection within the iframe still =
does not work)
8) not supported

There was a recent commit to provide a setting to force all whitelisted =
URLs to load within the UIWebView which may address some of the issues.  =
=20

What use cases do we want to support and how can we do that consistently =
across platforms?  =20
