Change Description Date Changed

New Feature

Lambda@Edge now enables you to further customize the delivery of content stored in an Amazon S3 bucket, by allowing you to access additional whitelisted headers, including custom headers, within origin-facing events. For more information, see these examples showing personalization of content based on viewer location and viewer device type.

New Feature

You can now use Amazon CloudFront to negotiate HTTPS connections to origins using Elliptic Curve Digital Signature Algorithm (ECDSA). ECDSA uses smaller keys that are faster, yet, just as secure, as the older RSA algorithm. For more information, see Supported SSL/TLS Protocols and Ciphers for Communication Between CloudFront and Your Origin and About RSA and ECDSA Ciphers.

March 15, 2018

New Feature

Lambda@Edge enables you to customize error responses from your origin, by allowing you to execute Lambda functions in response to HTTP errors that Amazon CloudFront receives from your origin. For more information, see these examples showing redirects to another location and response generation with 200 status code (OK).

New Feature
