/// User-Agent:
///
/// This is ignored from signing because signing this causes problems with generating pre-signed URLs
/// (that are executed by other agents) or when customers pass requests through proxies, which may
/// modify the user-agent.
///
/// Content-Length:
///
/// This is ignored from signing because generating a pre-signed URL should not provide a content-length
/// constraint, specifically when vending a S3 pre-signed PUT URL. The corollary to this is that when
/// sending regular requests (non-pre-signed), the signature contains a checksum of the body, which
/// implicitly validates the payload length (since changing the number of bytes would change the checksum)
/// and therefore this header is not valuable in the signature.
///
/// Content-Type:
///
/// Signing this header causes quite a number of problems in browser environments, where browsers
/// like to modify and normalize the content-type header in different ways. There is more information
/// on this in https://github.com/aws/aws-sdk-js/issues/244. Avoiding this field simplifies logic
/// and reduces the possibility of future bugs
///
/// Authorization:
///
/// Is skipped for obvious reasons
