| <tt>HttpAsyncRequestHandler</tt> represents a routine for asynchronous |
| processing of a specific group of non-blocking HTTP requests. Protocol |
| handlers are designed to take care of protocol specific aspects, whereas |
| individual request handlers are expected to take care of application |
| specific HTTP processing. The main purpose of a request handler is to |
| generate a response object with a content entity to be sent back to |
| the client in response to the given request. |
