Represents the context for the handling of a request in Vert.x-Web.
 A new instance is created for each HTTP request that is received in the Handler of the router. 

The same instance is passed to any matching request or failure handlers during the routing of the request or
failure.

The context provides access to the  and 
and allows you to maintain arbitrary data that lives for the lifetime of the context. Contexts are discarded once they
have been routed to the handler for the request.
 The context also provides access to the Session, cookies and body for the request, given the correct handlers in the application. 

If you use the internal error handler
