Support for S3 PreSigned POST

[murrekatt]

Any plans to support S3 PreSigned POST?

I see there is some code for pre-signing here, but this is not that browser POST upload form.

Thanks!

@murrekatt As you noticed there is support for both POST and PUT S3 signed urls.
But if I remember correctly they assume you want to story the entire BODY of your request in S3 (or update in case of PUT).
I don't even know how the multipart (form/browser file upload) can work? I guess the server and the client (the browser) need to agree on field names and the separators before hand so that the server (goamz code) can generate and sign the thing properly. Just thinking out loud. It is not going to be easy to debug mmmm. If you ever wanted to try it, use runscope or some proxy and capture the failing request to compare with the one that goamz was signed ....
