NSURLHandle
An object that accesses and manages resource data indicated by a URL.
Declaration
class NSURLHandleOverview
A single NSURLHandle can service multiple equivalent NSURL objects, but only if these URLs map to the same resource.
Overview
Cocoa provides private concrete subclasses to handle HTTP and file URL schemes. If you want to implement support for additional URL schemes, you would do so by creating a subclass of NSURLHandle. You can use NSURL and NSURLHandle to download from FTP sites without subclassing.
