LiveHTTPHeaders
8th April 2003
Via Sam Buchanan, Daniel Savard’s incredibly useful LiveHTTPHeaders addon for Mozilla and Phoenix. It adds an extra tab to the Page Info dialog with the full HTTP headers sent with the page, and also adds a HTTP Headers tool to the Tools menu which can be used to watch and debug HTTP requests in real time. I wish I’d known about this when I was developing HttpClient.
Incidentally, check out the headers on Slashdot for a particularly geeky in-joke ;)
