Changes to get NTLM Working With Appcelerator

app.js

var xhr = Titanium.Network.createHTTPClient();

// Set the property on http client, BEFORE OPEN
xhr.username = "ausername";
xhr.password = "apassword@1234";
xhr.domain = "adomain";
xhr.setRequestHeader('Content-Type', "application/json; charset=utf-8");

TiNetworkHTTPClientProxy.m

-(void)open:(id)args
{
	RELEASE_TO_NIL(request);
	
	NSString *method = [TiUtils stringValue:[args objectAtIndex:0]];
	[url release];
	url = [[TiUtils toURL:[args objectAtIndex:1] proxy:self] retain];
	
	if ([args count]>2)
	{
		async = [TiUtils boolValue:[args objectAtIndex:2]];
	}
	else 
	{
		async = YES;
	}
	
	request = [[ASIFormDataRequest requestWithURL:url] retain];	
    [request setDownloadCache:[ASIDownloadCache sharedCache]];
	[request setDelegate:self];
    if (timeout) {
        NSTimeInterval timeoutVal = [timeout doubleValue] / 1000;
        [request setTimeOutSeconds:timeoutVal];
    }
	
	if (hasOnsendstream)
	{
		[request setUploadProgressDelegate:self];
	}
	if (hasOndatastream)
	{
		[request setDownloadProgressDelegate:self];
	}
	
	[request addRequestHeader:@"User-Agent" value:[[TiApp app] userAgent]];
	
	// twitter specifically disallows X-Requested-With so we only add this normal
	// XHR header if not going to twitter. however, other services generally expect
	// this header to indicate an XHR request (such as RoR)
	if ([[url host] rangeOfString:@"twitter.com"].location==NSNotFound)
	{
		[request addRequestHeader:@"X-Requested-With" value:@"XMLHttpRequest"];
	}
	[request setRequestMethod:method];
	[request setDefaultResponseEncoding:NSUTF8StringEncoding];
	// don't cache credentials, session etc since each request might be to
	// different URI and cause security compromises if we do 
	[request setUseSessionPersistence:NO];
	[request setUseKeychainPersistence:NO];
	[request setUseCookiePersistence:YES];
	[request setShowAccurateProgress:YES];
	[request setShouldUseRFC2616RedirectBehaviour:YES];
	BOOL keepAlive = [TiUtils boolValue:[self valueForKey:@"enableKeepAlive"] def:YES];
	[request setShouldAttemptPersistentConnection:keepAlive];
    
    // NEW CODE ----
    [request setUsername:[TiUtils stringValue:[self valueForKey:@"username"]]];
    [request setPassword:[TiUtils stringValue:[self valueForKey:@"password"]]];
    [request setDomain:[TiUtils stringValue:[self valueForKey:@"domain"]]];
    // END NEW CODE --
    
	//handled in send, as now optional
	//[request setShouldRedirect:YES];
	[self _fireReadyStateChange:NetworkClientStateOpened failed:NO];
	[self _fireReadyStateChange:NetworkClientStateHeaders failed:NO];
}

This is great, how can it be done for Android?
