Subject: [undertow-dev] Async proxy to Async API
Hi everybody,
this is the big picture:
a. frontend application with Undertow
b. backend application with Undertow and Resteasy for REST API
A serves JS,HTML,CSS and exposes B's REST API with a proxy servlet (
https://github.com/mitre/HTTP-Proxy-Servlet ).
Since one method of my backend API does some image processing, I'm wondering
how to implement this method in an asynchronous way.
On B side I'm reading Resteasy documentation
http://docs.jboss.org/resteasy/docs/3.0.9.Final/userguide/html_single/#As...
On A side is there something could help me from undertow to proxy in async
way the requests to this method of B?
Use org.wildfly.extension.undertow.handlers.ReverseProxyHandler
The example io.undertow.examples.reverseproxy.ReverseProxyServer shows you how to use it.
Basically it works in the IO thread, so there is no dispatch to an executor required, and
both the incoming requests and async client connection both use the same thread for
maximum efficiency.
