How can I view HTTP headers in Google Chrome?

Till 9.x, the headers were under the resources in the Developer Tools, but now I can’t find it anywhere.

I’m not sure about your exact version, but Chrome has a tab “Network” with several items and when I click on them I can see the headers on the right in a tab.

Press F12 on windows or ⌥⌘I on a mac to bring up the Chrome developer tools.
