Subject Re: [users@httpd] SSL offload and load balancing with Apache2's mod_proxy and mod_balancer for Weblogic, Tomcat and Apache2
Date Sun, 06 Feb 2011 22:04:44 GMT
Hi Margus,

Yes, from your description "there 2 Apache instances running on the
same machine" I took it that these were running on the same machine.
Actually, I had assumed you were running ssl termination + load
balancer + destination web server all on the same box, and I was
wondering what the point was :)

If you are actually putting the different parts on different machines,
then this sounds fine.  The best configuration will depend on the load
in the different parts of your system.
