Desc of above code: When I started download by using downloadTaskWithURL It’s return expectedContentLength negative(-1) But that time resume data getting perfectly.

Another one is For solved above problem I'm using this below code

NSMutableURLRequest *aURLRequest = nil;
aURLRequest = [[NSMutableURLRequest alloc] initWithURL:aRemoteURL cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60.0];
[aURLRequest setHTTPMethod:@"POST"];
[aURLRequest setValue:@"identity" forHTTPHeaderField:@"Accept-Encoding"];

aDownloadTask=[self.backgroundSession downloadTaskWithRequest:aURLRequest];
