Troubleshooting an infinite redirect in a web application

Question

I have a web application that is trying to redirect in a loop, and Firefox is telling me that it is stopping because the request will never complete. Is there a good way (in Firefox) to see what URL is being requested in this never-ending loop? The address doesn't seem to appear in the address bar. Are there any addons that can help with this?

Answer 1

Firebug is an ever-popular choice. There is a console window that will show you all the various requests that your browser is making.

I'm also a fan of LiveHTTPHeaders which gives you a separate window that shows all the headers and request results. If your browser is making a lot of requests, you'll get a long log of them.

For the situation you describe, I'd probably go with LiveHTTPHeaders, as it logs all requests across all pages. Firebug is better on a per-page basis, and is more useful for checking out Ajax requests.

Answer 2

You could try Fiddler. It should show all http requests.

Absolutely, all you need is the tamper data plugin:
