Just a heads up, if you're running WAF with signatures and using updated Chrome, you might run into an issue with signature 999245, as the new version of chrome has added a value in the accepted-encoding called zstd. So you can disable the signature or create a copy and modify the signature request to

TEXT.CONTAINS(",").AND(TEXT.REGEX_MATCH(re/^(,{0,1}\s*(gzip|compress|deflate|br|identity|zstd|\*)(\s*;\s*q=[\d\.]+){0,1})+$/).NOT)

and make sure it's enabled again The orignal string is this:

TEXT.CONTAINS(",").AND(TEXT.REGEX_MATCH(re/^(,{0,1}\s*(gzip|compress|deflate|br|identity|\*)(\s*;\s*q=[\d\.]+){0,1})+$/).NOT)
