Upload a file with $.ajax to AWS S3 with a pre-signed url

When you read about how to create and consume a pre-signed url on this guide, everything is really easy. You get your Postman and it works like a charm in the first run.

Then you open your browser, try your usual $.ajax() and send your PUT operation, and you hit the cold iced wall of AWS error message, a simple <Code>SignatureDoesNotMatch</Code> that will steal hours from your productivity.

So here I come to save you and give you a free working example of how to upload a file directly to AWS S3 from your browser. You are wellcome :).

Safari iframe cookie workaround

Safari by default discards cookies set in an iframe unless the host that's serving the iframe has set a cookie before, outside the iframe. Safari is the only browser that does this.

The 10k foot view

In order to get around the issue, the parent (src) and child/iframed/remote (dest) site have to work together, if the source site only wants users to access the destination via the iframe and can't assume that the user has visited the destination host before.
