Of course they should probably escape any headers they get from the sites they pull the data from to avoid Cross-Site Scripting :) http://showmetheheaders.com/?q=www.mccune.org.uk

good catch. thanks! should have proper filtering now. that's what i get for writing code at 2am and not properly reviewing.

Looks like they do it with javascript + YUI which is pretty cool: http://showmetheheaders.com/static/showme.js

You can do it with curl too for all those who don't know

    curl -I example.com

works with multiple domains as well

you should send a user agent that makes it look like a real browser. for eg. Microsoft.com responses are different based on user agent, which is why they do the redirect. Here is Microsoft.com from Chrome (it is diff again for IE 6/7/8 etc.), you get a lot more information:

Is anyone else surprised that microsoft.com still has "emulate IE7" turned on?

slashdot.org gives you fortune output in an "X-Fry" header, much like the site itself.

EDIT: on second look, they're Futurama quotes. That explains why "X-Fry" changed to "X-Bender" when I went back!

TechCrunch is fun...

  # X-hacker If you're reading this, you should visit automattic.com/jobs and apply to join the fun, mention this header.

I'm guess thats because Techcrunch is hosted using wordpress.com's VIP service and that's wordpress.org/com's header

This is fun.
