Wasn't nginx just on hn a few days ago getting completely slammed for being a less than stellar proxy? When I hear almost completely different experiences and advice from people working with a product in production it makes me wonder how to properly assess it.
I guess people paint with a broad brush based on their experience. nginx is a pretty fantastic piece of software - it runs a significant proportion of the web. nginx retries put / post requests if the application server times out. This quirk can be dangerous if you don't know about it, and nginx really should allow you to configure it, but it can be patched, and only affects you if you have multiple application servers.
