POST Policy - Amazon Simple Storage Serv...
AWS S3 seems to have a feature called POST Policy (see: https://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-HTTPPOSTConstructPolicy.html#sigv4-ConditionMatching) which can be used when making signed urls for file uploads. R2's documentation does not really affirm or deny compatibility with this feature. Does anyone know if R2 supports the feature described in the link above? Such a feature would allow CF R2 to independently run pre-specified assertions on the request as part of the upload transaction.
