could you explain how mod_perl would handle routing capability to pass to tc
instances?..could mod_perl accomplish the functionality of a load-balancer?
It certainly could, but you don't have to go that far.
A mod_perl module could handle the original request (be it SOAP or REST
or whatever), then issue calls to whatever number of back-end Tomcats
using whatever interface /they/ provide. There is no question of
load-balancing here, you have to issue the requests to the back-end
Tomcats sequentially, as far as I understand.
Basically in this case, the mod_perl module could just issue Apache
internal sub-requests, and let the normal Apache and connector
mechanisms handle the details of the communication with Tomcat.
If you don't know mod_perl, think of it this way : it is just a
convenient perl API to the core Apache functionality. You can use it to
write add-on modules that intervene at each individual step of the
Apache request processing cycle, or not, as you wish.
