[OpenSIPS-Users] loadbalancer module and adding servers to the load balancing pool

[Bobby Smith]

I feel there can be something done using the ratelimit module here:
http://www.opensips.org/html/docs/modules/1.6.x/ratelimit.html, but I don't
see that happening without a way to do a "select next" with the loadbalancer
module.  Currently, the implementation calculates load based on resources
available, but is there a way to forcibly skip a resource and pick the "next
best" resource, like a lb_do_next() function?

Thanks,

Bobby Smith
