Function: A URL session task that is stream-based.
NSURLSessionStreamTaskMBS is a concrete subclass of NSURLSessionTaskMBS. Many of the methods in the NSURLSessionStreamTaskMBS class are documented in NSURLSessionTaskMBS.
The NSURLSessionStreamTaskMBS class provides an interface a TCP/IP connection created via NSURLSession. Tasks may be created from an NSURLSession using the streamTaskWithHostName and streamTaskWithNetService methods. They may also created as a result of an NSURLSessionDataTaskMBS being upgraded via the HTTP Upgrade: response header and appropriate use of the HTTPShouldUsePipelining option of NSURLSessionConfigurationMBS.

See RFC 2817 and RFC 6455 for information about the Upgrade: header.
An NSURLSessionStreamTask object perform sasynchronous reads and writes, which are enqueued and executed serially, calling a handler upon completion being on the session delegate queue. If the task is canceled, all enqueued reads and writes will call their completion handlers with an appropriate error.

When working with APIs that accept NSStreamMBS objects, you can create NSInputStreamMBS and NSOutputStreamMBS objects from an NSURLSessionStreamTaskMBS object by calling the captureStreams method.
Subclass of the NSURLSessionTaskMBS class.
