Re: Prior Art
I didn't say interchangeable, just that they have common roots. Though they are indeed sufficiently similar that pretty-much anything from Apache 1.3 just needs "changing the plug" to port to nginx.
In fact nginx is probably closer to Apache 1.3 than either of them is to Apache 2.x, but that's because of the different directions the servers have taken, with Apache 2 having added things like its more sophisticated filtering, database connection pooling, etc.
Yes, some of it is entirely different: nginx was way ahead of apache in adopting an event-driven core processing model (which may well have been Syseov's #1 motivation for a new server). But if you want to make an IP claim, you'd have to figure out what's new vs what's adopted from elsewhere. I was wondering whether Rambler has undertaken that not-inconsiderable task.
