问题 Is there a way to do a multipart upload via the browser using a generated presigned URL? 回答1: I was managed to achieve this in serverless architecture by creating a Canonical Request for each part upload using Signature Version 4.

问题 I am using FastImage for caching image and it loads image very fast after caching data as expected. But my server is generating new uri (s3 presigned url) each time for same image.
