A.The advantage of the Apache R-proxy method is that it can be set to realize that apache is responsible for processing static web pages, and Tomcat is responsible for processing dynamic requests such as jsp and server.

B.The Apache R-proxy method means that when one of the Tomcats stops running, Apache will forward the request, resulting in a 502-gateway error, but this problem does not exist as long as the server is restarted.

C.The disadvantage of Apache R-proxy is that when the stopped Tomcat server is restarted, Apache cannot detect it and will not forward the request.

D.In Apache modk mode, Apache will automatically detect the stopped Tomcat server, and then no longer send requests in the past.
