It also tries to read through the Javascript served up to see if it uses browserify. https://github.com/dotheyusenode/dotheyusenode/blob/master/c...
But yes it is a glorified `curl -I www.foo.com | grep -i 'x-powered-by` UI
You probably might want to stick "-s" in there too; silence the transfer statistics which curl (annoyingly) adds when output is piped / redirected.
Yeah I saw (I had a browse through your source after your previous post).
As a side note, I was impressed with just how readable your code was (even for someone like myself with very poor Javascript skills). I can't comment on how much credit node.js deserves for that, but I've seen people turn even the most readable of languages into line noise in the past. So it's always a pleasure to read code that doesn't require lines of comments to explain their function.
