On August 27th, 2008, Bill Benac published a very useful Firefox Add-on. With this add-on you can always recognize the portal server the response came from. Especially it is very useful in a clustered environment.


My colleagues and me extended this add-on with additional information, like the construction and response time. You can get this add-on from Bill Benac's website http://blog.billbenac.com/blog/2008/08/firefox-plugin-shows-host-port.html or send me a mail .
