Upload File while application in background : ASIHTTPRequest with Phonegap

I am using the ASIFormDataR开发者_C百科equest for uploading file on server.

I am using ASIHTTPRequest to achieve the functionality of upload in background.

It working fine. But When application going to background then it fail to upload the file.

I try a lot of test with my code, even sometime it works for background too.

When I am uploading file and application going to background and then application again active then it upload successfully.

I notice that (but not sure) if application going in background for time more than the request time out time then it fail to upload. (I am not sure about it)

NSString *filePath = [arguments objectAtIndex:0];
NSString *fileName = [arguments objectAtIndex:1];

NSURL *url = [NSURL URLWithString:@"http://192.168.1.107/~amitb/test/upload.php"];
NSData *imageData = [[[NSData alloc] initWithContentsOfFile:filePath] autorelease];

ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
request.delegate = self;
[request setData:imageData withFileName:fileName andContentType:nil forKey:@"file"];
[request startAsynchronous];

Can anybody help me to upload file while application in background

http://allseeing-i.com/ASIHTTPRequest/How-to-use#background_downloads_ios states that you can use:

[request setShouldContinueWhenAppEntersBackground:YES];
