>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: WP8
>    Affects Versions: 3.0.0
>         Environment: Development Environment: Visual Studio 2012 (with Update 3), Windows
8 x64, 
> Target Environment: Windows Phone 8.0
> Other libraries - jquery, requirejs
>            Reporter: Shashank Banerjea

> In the WP8 application we are developing, when the following code is being executed -
> {panel}
> $.get("/www/folder/to/devConfig.txt").done( function(content) {
>   settings = JSON.parse(content)
> } );
> {panel}
> I get the following exception:
> {System.InvalidOperationException: This operation is not supported for a relative URI.
>    at System.Uri.get_AbsolutePath()
>    at WPCordovaClassLib.CordovaLib.XHRHelper.HandleCommand(String commandStr)
>    at WPCordovaClassLib.CordovaView.CordovaBrowser_Sc...
> I tried various combination such as:
>  - "file:///www/folder/to/devConfig.txt" and "file://localhost/folder/to/devConfig.txt",
which translated to "/www/folder/to/devConfig.txt", in the relative path.
> In these cases I received a 404 error.
> Reading through the documentation, it seems that the first "/" needs to be removed for
the relative path to work, instead of "/www/folder/to/devConfig.txt" should be "www/folder/to/devconfig.txt".
> Sending "www/folder/to/devconfig.txt", causes the first exception.
> As a fix, I have modified the XHRHelper code to check for isAbsoluteUri condition and
remove the first "/" if it is a relative path. That seems to work. But it is not a future
proof solution.
> Please advise.
