Pingdom monitoring tool detecting HTTP 302 Found responses intermittently
===

I am experiencing intermittent issues when using the [Pingdom][1] monitoring tool to check the status of my website.

Every 10-15 minutes I get an alert to say that a 302 has been found. What I can't understand is - i'm not doing any 302 temporary redirects. I am, however, doing 301 redirects (in certain circumstances).

Could this be a false positive from Pingdom?

Also, I have a redirect in code that does this. Would not specifying the HTTP response code
cause an issue here?

    header('Location: http://www.ayrshireminis.com');
    exit();


The Pingdom data:


    Request 1
    GET / HTTP/1.0
