Traffic forwarding.....

[Charles W Buege <cbuege@xxxxxxxxxxxxx>]

All - 

I've got HA working for Apache and also
reverse proxy working as well.  You can see the attached JPG for my
layout.  

10.1.12.11/10.1.12.12 have a heartbeat
between them keeping the virtual IP address 10.1.12.10.
The httpd services on both .11 and .12
are only configured to proxy forward to the next apache servers depending
on what the incoming host name is.  If the incoming traffic is going
to www.avengers.org,
it forwards the traffic on to 10.1.12.4 (set in the hosts file on each
of the proxy/high availability machines).  If the incoming traffic
is going to site2.avengers.org, then it goes to 10.1.12.6.  The client
always only sees these two web sites as 10.1.12.10.

Here's what I'd like to do now:  If
there is an incoming connection to www.avengers.org
that is going to port 3306 (MySQL) for example, how can I configure the
system to pass this information along?

In reality, what I'm trying to figure out how to do is, with my existing
configuration, how to pass traffic that ISN'T 80 or 443 on to the right
host depending on the incoming host name.  In my actual production
environment, I will have some web services running on some of the servers
and I'm trying to avoid moving them all to different IP addresses so I
can keep the DNS information the same as it currently is.  So, I guess
what I'm saying is how can I use the single IP address of 10.1.12.10 pointing
to either host name and have Apache proxy pass the data along to the proper
server depending on the incoming request.

I may be all wet and my idea may not
even work.  Go ahead and yell at me if I'm trying to do something
impossible.

If my question doesn't make sense, please
feel free to ask for more details and I will share as best as I can.

Thank you,
Charles
