nginx is another interesting HTTP server
This happens to have been the HTTPd of choice of the authors of stormworm, the much discussed malware. It's in fact so unique, many vendors chose to trigger IDS on its banner.
For example:Cisco Intellishield
Edit: Changed tense
I like this part:
quote:nginx seems to have done it right: a small amount of processes each using epoll. If the kernel doesn't waste a whole heap of memory with each open connection, this would scale really well.
Because web connections arent as long lived as IMAP connections, we stayed with Apache for our frontends for a while longer. However weve now switched over to using nginx for our frontend web proxy as well, which has also allowed us to increase the keep-alive timeout for HTTP connections to 5 minutes, which should result in a small perceptible improvement when moving between pages.
The net result of all this is that each frontend proxy server currently maintains over 10,000 simultaneous IMAP, POP, Web & SMTP connections (including many SSL ones) using only about 10% of the available CPU on 3.20GHz Netburst Xeon based CPUs.

dammit .. now I read some more about nginx, I want to change our front end. Which means converting a bunch of ReWrite rules, testing and so on and so forth.
But since it offers proper limits per simultaneous IP and such huge scalability and such immense capacity for KeepAlive and open but quiet connections, I can't see why to stick with apache2
