If HTML is too big, the sub-library "simple_html_dom" fails because the limit is 60k. Increasing that limit on the other hand can also [cause trouble](https://github.com/rosell-dk/webp-express/issues/328#issuecomment-534108474). It comes down to that...

If the test returns webp when it should not, examine the headers. Look for something like this: ``` server: keycdn-engine status: 200 strict-transport-security: max-age=31536000 x-cache: HIT x-edge-location: nlam x-shield: active...

For example before creating the rewrite rules, a live test could be made.
