“Firefox has detected that the server is redirecting the request for this address in a way that will never complete”

Getting error "Firefox has detected that the server is redirecting the request for this address in a way that will never complete" can be very disturbing for a web developer when he has tried to modify something. This can left you clueless about what need to be done! I got this error when I have modified main.php file for a PHP framework. I got this error earlier also but I forgot that.

Code was written like this:

$request_url = $_SERVER['REQUEST_URI'];

if request url fulfills the criteria
then
remove that criteria from web address and further redirect to new web address.

What happened is - I removed the criteria by programming mistake. Whatever left become finally like this:


A Web Address is redirected to the same Web Address!
and this results in a loop - A Web Address to the same Web Address. Right!

You know Firefox browser is clever. So, it redirects few times and shows error -
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.
But IE keep on trying and you are completely clue less about your web page. What went wrong about your modification on the page!
