I would like to test Cloudflare Polish (want to try WebP for images), but my Director of UX is very concerned that this could “break” the site. I think I already know the answer, but he’s asking if we could test a limited number of pages or some type of whitelist rather than the whole site.
If this is not possible, I recommended that we could turn Polish on or off at will, but it will require the cache to be cleared. I’ve run a variety of metrics on 32 URLs and would plan to retest them with Polish turned on.
How can I run a “safe” test that wouldn’t freak him out?
