[QUOTE="Nethfel, post: 1259912, member: 89124"] You need to implement the delegate methods that actually will store the data. You need to store the NSMutableData object as an IVar and not a local variable in that method that you create the request. Since this is an ASYNC request, data will be received in the background while your app is allowed to continue to run. The delegate methods give you the ability to store the data as it arrives, reset the data when appropriate, complete the process when appropriate and provide error messages should there be a problem. You need to read this page: [url=http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/URLLoadingSystem/Tasks/UsingNSURLConnection.html]Loading[/url] that will give detailed information on the delegate methods you need to implement. Just remember, you won't have valid data where you're currently doing the length test. [/QUOTE]
