I am acutely aware of HAProxy however the rest of the team is, no surprise I'm sure, familiar with nginx. Likely I'll end up doing the usual nginx->haproxy->backend chain again. HAPROXY appears to have an enterprise now(it may have had forever I just have not noticed) but it appears to be much more focused on value-add support and stack validation than hiding simple-to-implement stuff behind a paywall and open-core. This is more of a frustration with nginx which could be so much more for us if:

* They were not purposely holding back features so they can be pay-walled

* Re-compiling were not necessary to add functionality

* More cohesive modification ecosystem

I know I said "reverse proxy" which HAProxy is cleary the more superior, but I didn't mean to limit my statement to reverse proxies. nginx does have a lot of other functionality people rely on..
