I am experiencing intermittent issues when using the Pingdom 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
User-Agent: Pingdom.com_bot_version_1.4_(http://www.pingdom.com/)

    Looks to me like a cookie is being set on the response, then redirecting you to the same page. Because Pingdom uses a number of different monitoring sources, that cookie redirect behavior will cause a lot of problems. Then again, you may need it for actual website visitors.

    Rather than monitor the root of the webpage, I would recommend creating a separate /status page just for Pingdom that:

    1. Doesn’t set or use cookies
    2. Performs a cheap end-to-end health check of the application and backing services
    3. Returns a 200 response code only if everything checks out OK
