I have a bug in my code causing "page isn't redirecting properly". Is there any way to debug this? I tried profiler thinking it would show the spot in the code where i was stuck in a loop; but no luck.

Browsers will often detect a redirection loop and show an error like that.

It is often caused by Apache rewrites in .htaccess, which means they do not get as far as PHP and the debugger won't help you.

Do you use an .htaccess file with any sort of rewrite or redirection?
