[TIMOB-519] problem with this in callbacks for XHR

Sample code to reproduce:

   var client = Titanium.Network.createHTTPClient();
   client.onload = function() {
       Titanium.API.info("Loaded! Status: " + this.status);
   
       var contentType = this.getResponseHeader('Content-Type');
       Titanium.API.info("Content-Type: " + contentType);
   };
   client.open("GET", "http://example.com/");
   client.send();
   

got on iphone:
[INFO] Loaded! Status: 200 [INFO] Content-Type: null <- BROKEN

got on android:
I/TiAPI (11249): (kroll$1) [23,606] Loaded! Status: 200
I/TiAPI (11249): (kroll$1) [13,619] Content-Type: text/html; charset=UTF-8 <- fine

Several related issues also mentioned on https://appcelerator.lighthouseapp.com/projects/32238-titanium-mobile/tickets/1502-httpclient-problems-with-header-parsing-and-responsedata-in-onerror-handler"> https://appcelerator.lighthouseapp.com/projects/32238-titanium-mobi...

Isn't this somewhat critical? Does anyone have a patch for it?

Just checked the sample code provided by Brion Vibber against 1.5 on simulator with the following address:
http://developer.appcelerator.com/apidoc/mobile/1.4/api.json">http://developer.appcelerator.com/apidoc/mobile/1.4/api.json

The console returs:
[INFO] Loaded! Status: 200 [INFO] Content-Type: text/json

Ticket resolved

Using mobile sdk 1.6.1 and iOS (any version), this problem persists depending on which version of Apache is running on the server. Is there any way to collect the raw headers and parse them myself? I believe getAllHeaders is not supported in iOS still.
