If this propagates all the way up the call stack the exchange will be ended with a response code.

 

Exchange attributes may have up to two textual representations, a long one and a short one.

 

This limit is necessary to protect against hash based denial of service attacks.

The Servlet specification only allows you to specify a single mechanism name, while Undertow allows as many as you want if you are using Wildfly you can make use of this by using a comma separated list of names in web.

 

An Undertow server is basically composed of three things, one or more XNIO worker instance, one or more connectors, and a handler chain to handle incoming requests.

 

A list of the built in attributes provided by Undertow is below:.

 

Security Handlers Security within Undertow is implemented as a set of asynchronous handlers and a set of authentication mechanisms co-ordinated by these handlers.

 

I chosen it because, while learning, you can compare it with traditional MVC style application.

 

You can set options with the Undertow.

 

This handler can take a Predicate that makes a decision about if the request requires authentication.
