Redirect Loops – How browser detects?

Recently I could stopped at a Firefox internal page warning me of Redirect Loop. The one which you see below.

So, What is a Redirect Loop?

From the name you could easily understand that redirects just keeps on looping between a couple of webpages and doesn’t land in any of the webpage. These kind of redirects are termed as Redirect Loop.

The HTTP Standard states that a client browser should detect a infinite Redirect Loops. But some of the clients ( like Firefox, Internet Explorer ) just tries with limited number of redirects and then finally drops a warning page like above ( in Firefox ).
