Issue #
Closes aws-sdk-kotlin#862
Description of changes
Recent changes #802 and aws-sdk-kotlin#845 enabled sending the
Expect: 100-continue
header on S3 PUT requests over 2MB (by default). TheExpect
header is not meant to be signed and causes a problem when using S3 with Transfer Acceleration enabled. (It is unknown why this doesn't also cause a problem when using the default S3 configuration.)This change exempts the
Expect
header from signature calculation.By submitting this pull request, I confirm that my contribution is made under the terms of the Apache 2.0 license.
