Hi guys,

Could you give me a hint if there is a way to write asynchronous handlers?
So, I have my own asynchronous runtime (namely ZIO) and I wish undertow's worker thread to do something while it's waiting for request completion after a `dispatch` in my handler.

Is there an API allowing me to return a Future or undertow's IOFuture so I may write an adaptor for my primitives?..

From what I can see there is that zero-arg `.dispatch()` method which just changes internal flag. So, from what I can understand I may just set that flag and then complete my request totally asynchronously. Though that method is marked deprecated without an alternative - other versions also wait for a `Runnable`.

In general you should not used the no arg version of dispatch(), it has been deprecated as it is not thread safe. 

If you want to just dispatch some work to a worker using the version that takes a runnable sounds like exactly what you are after, as it will run the runnable in a worker thread.
