Don’t modify the URL provided

If you modify the URL in any way (change to the FQDN, capitalize a lowercase letter, forget to add a period, etc.), we won't be able to find the verificationtoken.txt file with our generated random value in it.

For example, if we provide you with this URL:]/.well-known/pki-validation/verificationtoken.txt, do not add www to it or capitalize any letters that were not capitalized in the original URL.
