Publishing to Amazon S3 with Espresso

I've been looking around to get some clarity on this but it seems like I'm the only stupid one having a problem with it.

Case is, I can't connect to Amazon S3 with Espresso. Or I think the case is rather that I don't know how to. I mean, I have my username, access key and secret key. Espresso asks fo开发者_JS百科r the username and password. So which one is my password? What should I use as the "server"? The port? I just can't make it work.

Sorry for being stupid but please help me out here. I know there are many of yous who use both Espresso and Amazon S3.

Many thanks in advance.

Way old question, but for the ones (like me) who googles it and ends up here, I found out how to make it work:

Server: s3.amazonaws.com

User name: Your access key

Password: Your secret access key
