Allow cachebusting URLs
I use updown to check a url that is behind a caching CDN. If the origin server goes offline, real users making requests for new URLs will see errors, but I will not be notified of downtime: the updown check will still succeed since the URL it is checking has been cached.
I'd like the ability to add a random string to a URL each time it is checked, so that requests bust through the cache and check that both the CDN and origin server are online

Indeed that’s a classic problem but it’s better solved using the standard Cache-Control header to disable caching, and this one can already be set on updown.io using the customize request form (</> icon).

I think this shouldn't be declined.
We use static site caching too. Using a “random” request parameter would be the simplest method, which doesn't need any advanced technical knowledge.
Also, this parameter than could be used for the contains check too.
