gotcha,
so on the config i have a question on the setup, this is what i think i
should have
# Main listening ports
ListenHTTP
Address 192.168.3.120
Port 80
End
Service
BackEnd
Address 192.168.3.120
Port 8080
Priority 5
End
Address 192.168.3.118
Port 80
Priority 4
End
Address 192.168.3.119
Port 80
Priority 3
End
Address 192.168.3.102
Port 80
Priority 2
End
End
i have pound on a machine that is also a webserver, so that way i can utilize
apache on that same machine that is why i have one of those set to port 8080,
will this work

have pound deligate what servers is being used
Eirik has a point that sometimes it is better to separate your
applications. I am in the camp that unless you have some specific
reason to split things up, reliability & redundancy trump most other
goals, so I say use all 3 servers and split things up with pound.
Assuming you don't have any sort of shared storage (i.e. NFS, etc),
you would need to copy all the application code across the servers.
You do need a method to share session data (maybe a DB or something)
if you intend to allow sessions to migrate between backends.
Basically if you're going to use 3 servers in a round-robin format,
you need to configure the servers so that at any moment any one can
serve any request. Every server must have access to the sessions and
any other code or data the other servers have. The advantage here
over using sticky-sessions is that problems with one backend become
obvious quickly. With sticky sessions, if you want to figure out why
a certain backend is doing something, you first have to either setup
pound to isolate the backend or figure out some other way of hitting
it directly. With round-robin, you just hit reload in your browser a
few times.
