>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: WP8
>    Affects Versions: 3.8.1
>         Environment: -Windows 8.1, Visual Studio 2013 Pro, Cordova 5.1.1, wp8 3.8.1
> -NOKIA Lumia 1520, Windows Phone 8.0

> wp8 platform builds do not successfully complete ajax requests.
> Note: The 'Affects Version' picker when creating this issue report did not allow me to
use the actual version of 3.8.1.  I picked the 'unreleased' version of 3.8.0, however, 3.8.1
is the version that is given by default when adding the platform and is listed as a release
in github.  
> *Client Setup*
> 1. Add wp8 platform: {{cordova platform add wp8}}
> 2. Add jquery as a dependency in {{index.html}}.  I used a local copy and did not try
cdn.  
> 3. Change Content-Security-Policy in {{index.html}} to have {{'default-src' *}}
> 4. Change {{index.js}} to the following in order to add tests
> {code:javascript}

> *Server Setup*
> I created a simple sails.js server for the test, but am using a client's IIS server in
production.  Use any server for reproducing.
> 1. Install node.js
> 2. Install sails: {{npm install -g sails}}
> 3. Create sails app: {{sails new testAjaxServer}}
> 4. Create controller file for testing {{<root>/api/TestController.js}} and populate
it with 
> {code:javascript}
> module.exports = {
>   test : function (req, res) {
>     sails.log("Got a request");
>     res.send('{"result":"hooray!"}');
>   }
> };
> {code}
> 5. Run the server from the root directory of the sails app: {{sails lift}}
> 6. Test server by visiting {{localhost:1337/test/test}}.  You should see the json result
that is specified in the test controller.
> *Expected*
> Loading this {{index.html}} in chrome and running {{testConnections()}} produces the
correct output as shown below.
> {code}

> *Actual*

> {code}

>   "wrappedXHR": {},
>   "readyState": 1

>   "status": 200,
>   "statusText": "parsererror"

> {
>   "wrappedXHR": {},
>   "readyState": 4
> }
> GET: error in onload
> {
>   "wrappedXHR": {},
>   "readyState": 4

> {code}
> The jquery functions have a 200 response, but fail due to a 'parserror'. There is no
response text.  The vanilla js tests fail for an undisclosed reason.  The server logs indicate
that there was never any established connection.  I am able to hit my server from the phone's
browser and get the json response.  
> Interestingly, when running the test in IE11 I get the following error: {{SCRIPT7002:
XMLHttpRequest: Network Error 0x2efd, Could not complete the operation due to error 00002efd.}}.
 There could be a similar error occurring in the device, but I am not sure how to capture
it.  In any case, I believe that I have followed all of the documentation for settings up
the test project for using ajax calls, so if there is other configuration required then at
least there needs to be a doc update.
