Amazon SageMaker might add additional headers.

For information, see <a href=\"https://docs.aws.amazon.com/AmazonS3/latest/API/sig-v4-authenticating-requests.html\">Authenticating Requests (AWS Signature Version 4)</a> in the <i>Amazon S3 API Reference</i>.</p> <p>A customer's model containers must respond to requests within 60 seconds. The model itself can have a maximum processing time of 60 seconds before responding to invocations. If your model is going to take 50-60 seconds of processing time, the SDK socket timeout should be set to be 70 seconds.</p> <note> <p>Endpoints are scoped to an individual account, and are not public.
