Subject [jira] [Updated] (CB-1406) HTTP-Get via XHR in Web Workers always return status 0 under iOS 6 (Beta 4)
Date Sun, 02 Dec 2012 18:25:58 GMT

Jochen Magnus updated CB-1406:
------------------------------

    Attachment: workertest-native.zip

Shazron,

I can confirm that the problem is caused by UIWebView and not by Cordova. I made a sample
program using a simple UIWebView with the same JS code but without the use of Cordova: the
same violation of the Same Origin Policy happens. Probably due to a wrong HTTP header.

I filed a bug (#12793598) to Apple and I hope this time it is not like exposing a message
in a bottle...

> HTTPRequests in the Web Workers ending always with http.readyState==4  (that's the ready
state) but with http.status==0, which is an undefined status (normal is 200 for "o.k."). The
file is requested from and fully deliverd by the webserver. 
> This happens under iOS 6 Beta 4 but not under iOS 5.x where the same app with the same
Cordova version works well.
> The problem did not occur with XHR in the native programs main thread nor in non-native
HTML5-apps (WebApps without the use of Cordova). 
> A Xcode test project is available.
