Cloudfront

A signed URL includes additional information, for example, an expiration date and time, that gives you more control over access to your content. This additional information appears in a policy statement, which is based on either a canned policy or a custom policy.

You can use CloudFront to automatically compress certain types of objects (files) and serve the compressed objects when viewers (web browsers or other clients) support them. Today I will show how to do it in AWS CDK.
