If I visit http://www.endsleigh.co.uk/Pages/Endsleigh-App.aspx then the request completes with a URL of https://www.endsleigh.co.uk/personal/

When this kind of thing has happened before with other sites, I've seen 3xx responses in Firebug, followed by the request to the second URL. But this time I don't see that, and Firefox's Live HTTP headers add-on doesn't show this either. It's as if I'd never typed in the first URL.

Then I tried it in Chrome, and saw a 301 redirect. Why would this be shown in Chrome but not in Firefox's native tools or headers add-on or indeed in Firebug?

  • I just tried it on chrome and firefox, but on both browsers, I get redirected immediately without seeing any 301 redirect. Maybe it is the speed of the connection, you see it on Firefox when the network is slower? – vinnief Dec 19 '13 at 21:39

    It could be because the 301 redirect is cached by Firefox. You could try clearing the Cache via History (Alt + S) > Clear Recent History with an appropriate Time range to clear. Alternatively, Forget About This Site via the History library. Clearing cache/history – vWil Dec 20 '13 at 0:03

It's hard to explain why firebug would not show the header. I would clear the cache, make sure accessibility.blockautorefresh=true, and lastly use the NoRedirect addon. You can then add two custom rules, leaving unchecked all three checkboxes


or perhaps even one regex rule as in this image:

I would hope after these 3 changes, that firebug would finally record the sent header.
