...Read the HTTP headers? I think you answered your own question.
- maw 15y agoI think GP meant that they hide that info even in their headers, such that you can't just see what's in Server:.

- JonoW 15y agoAs @maw said, most top sites remove the http headers that identify the web-server. Also, if you had to take the top, I don't know, 10k sites by traffic, I would imagine all of them use a load-balancer, so how can netcraft know what the web-server is behind them?
- chc 15y agoTop sites? I think probably a few of these would quality: CNN.com — Server: nginx Netflix.com — Server: Apache-Coyote/1.1 YouTube.com — Server: Apache Wikipedia.com — Server: Apache Twitter.com — Server: tfe LinkedIn.com — Server: Apache-Coyote/1.1 Granted, this does not give you a good picture of their network topology, but in general they do report something that Netcraft can use.
- mst 15y agoRight. The version is often stripped out, but the server software tends to stay in there. Totally possible there's extra heuristics in there though; I totally can't remember from when I ran that thing but it took about a week to run and spent most of its time waiting on other people's servers, so burning a bunch more CPU doing extra analysis wouldn't cause Netcraft any issue at all, I don't think.
