In building a backend system to recreate and verify client request before signing them, I noticed the AWS SDK for PHP have blacklist of headers for those it will not sign.
As such, I have removed the content-length header from AwsSignatureV4.prototype.canonicalHeaders function to align with AWS's signature process.
