@arc002 ajaxify.data is just the data the template was run with. Changing it does nothing to the already rendered page.
What you want is to add a hook for filter:topics.getand modify the data there.
config.json setup can be automated via environmental variables using hash__value. However, how do we set ports?
In this case, I'm wanting to set the port attribute for load balancing (i.e., port: "[4567, 4568, 4569]")
@matti Err... I'm not quite sure whether that is possible. What values have you tried?
