Tip: Tracking HTTP headers

There is a lot of HTTP communication that takes place everytime you hit a URL, a request goes to the web server and the response reaches back to your browser in seconds (if you are having a good day and have a good internet connection).

For developers debugging a web application, its really helpful sometimes if you could know what exactly is happening in the background.

livehttpheaders and ieHTTPHeaders are two utilities that show you the HTTP Headers on Firefox and IE respectively and even tell you what kind of web server the remote site is using.
