[Zope] OT - *very* useful mozilla tip

[Seb Bacon]

Fairly off-topic, but I simply had to share this because it is very 
useful indeed for debugging:

http://livehttpheaders.mozdev.org/:

The goal of this project is to adds information about the HTTP headers 
in two ways:

     * First by adding a 'Headers' tab in 'View Page Info' of a web page.
     * Second by adding a tool in the 'Tools->Web Development' menu to be
       able to display http headers in real time (while pages are being
        downloaded from the Internet.)
     * Third by letting you edit request headers and replay an URL
       (beta). Look for the Replay button in the live window!
