[undertow-dev] SSL client authorization -- how ?

What are the detailed configuration instructions to configure "standalone.xml", web.xml, and jboss-web.xml to set up SSL with client authorization? Could someone direct me to the appropriate place to find detailed configuration information on how to have a WildFly 8.2 server evoke from a client, a certificate under SSL. The cerificate, I expect, would be sent via the "javax.servlet.request.X509Certificate" request attribute. If this is an inappropriate forum for this question, please feel free to direct me to the correct forum. Thanks in advance for your help.
