Subject: Re: [users@httpd] SSL offload and load balancing with Apache2's
 mod_proxy
 and mod_balancer for Weblogic, Tomcat and Apache2

Hello!

Thank you for your response! Glad to hear that I am not the only, who 
has thought that this solution would make life easier.

Taking Apache-Event into use in our case is not an option, as 
Apache2-mpm-itk is used (proccesses running in different user rights) 
and new TCP connection has to be started for new client - it would be 
possible to assign different IP-s for different hosts, but named hosting 
is much easier to configure.

If you would be so kind and take a look at the documentation also and 
give your oppinion: 
https://apache2-ssloffload-and-loadbalance.googlecode.com/svn/trunk/Documentation/apache2_ssloffload_and_loadbalance.pdf

Page 3 contains summary - how it works - and most of it is automatic 
install + configuration by copy-paste to bash.
