[users@httpd] mod_proxy ProxyPass balancer:// with SSL

[Cameron Taggart <ca...@gmail.com>]

I'm trying to connect httpd 2.2 to tomcat 5.5.12 in such a way that:
1) I can load balance multiple Tomcat instances.
2) If one Tomcat instance stops responding or is shutdown, it is no longer used.
3) Sticky sessions.
4) http & https (SSL) support

The first three items look like they can be accomplished using
mod_proxy and ProxyPass with a blanacer:// and ajp:// URL's to the
Tomcat instances.

Based on http://httpd.apache.org/docs/2.2/mod/mod_proxy.html#proxypass,
something like this may work:

<VirtualHost *:80>
   ServerName myhost.mydomain.com
   ProxyPass / balancer://mycluster stickysession=jsessionid nofailover=On
   <Proxy balancer://mycluster>
       BalancerMember ajp://server01:8009/myapp/
       BalancerMember ajp://server02:8009/myapp/
   </Proxy>
</VirtualHost>

Is it possible to add SSL into the mix and still have load balancing
and sticky sessions?  Any help or reality checks would be appreciated!

Thanks,
Cameron
