[dancer-users] Number of Nginx vs number of Starman?

[Jesse Thompson]

One of the things that keeps me tied to Apache is Mod Perl's ability to 
hook into the HTTP request cycle in interesting ways.

http://blog.zjt.im/2014/04/custom-load-balancing-with-modperl.html

My load balancing requirements include the ability to fail the 
connection if a health check response to a noop fails if it takes longer 
than several seconds, which is an indication of the upstream server 
being offline (long TCP timeouts!) or the upstream server is slow due 
load or having just come online.  In-band/passive health checks aren't 
adequate because you have to set the timeout to be longer than your 
longest "normal" request (which in my case, is very long) in order to 
prevent the load balancing algorithm from taking your upstream servers 
out of the cluster when there is no outage.

Some day, I would like to move to Nginx, but I would need to figure out 
how to implement a similar hook into the HTTP request.  Maybe it's 
already possible?
