title: AFNetworking 3.x what is the different between AFHTTPSessionManager and AFURLSessionManager?
body: <p>I'm about to upgrade <code>AFNetworking</code> from 1.x to 3.x. My question is what is the different between <code>AFHTTPSessionManager</code> and <code>AFURLSessionManager</code>? and when to use each? Which one support both <code>XML</code> and <code>JSON</code> request and response? Thanks</p>
