IAmazonS3: Generating cache-friendly presigned URLs

[miroljub1995]

Describe the feature

We would like to generate cache-friendly urls so browsers could cache response if signing time is short.
Right now URL has X-Amz-Date parameter which is a problem to cache.

There is a workaround for nodejs, but it is little hacky and wouldn't do it like that even if it can be done in dotnet.

Use Case

Cache responses when signing time is short (short in the context of the business logic).

Proposed Solution

No response

Can you explain what you mean by "signing time is short"? Do you mean using credentials that'll expire soon? Because if that's the case caching won't really help, the download would fail by the time the content is downloaded...

By short time I mean calling GetPreSignedURLAsync frequently.
I found out that AmazonCloudFrontUrlSigner.GetCannedSignedURL creates stable URLs that are cache friendly.
Also analogy is different, cf.GetCannedSignedURL accepts expiresOn, but s3.GetPreSignedURLAsync accepts Expires which is totally different (expiresOn = now + Expires).
