Using Amazon S3 with Dojo has the following prerequisites:

    * You must be signed up to use Amazon S3. You can sign up for Amazon S3 at http://aws.amazon.com/s3.

    * Use the provided proxy (/dojox/rpc/s3/proxy.php) with PHP 5.

    * proxy.php requires the following modules:

          o Crypt_HMAC

          o HTTP_Request

To use S3 from Dojo, you need a proxy. You can use the provided proxy example file by renaming 

proxy.example-php to proxy.php and then you must enter your Amazon access key and secret access key

into the proxy.php file on line 3 and 4:

$accessKey = "access key";

$secretAccessKey = "secret access key";

You then use the Dojo RPC service with the "PROXIED-PATH" envelope:

dojo.require("dojox.rpc.Service");

dojo.require("dojox.rpc.ProxiedPath");

var s3Buckets = new dojox.rpc.Service({

	target:"http://s3.amazonaws.com/",

	proxyUrl:"../s3/proxy.php", // the path to the proxy

	transport:"REST",

	envelope:"PROXIED-PATH",

	contentType:"application/json",

	services:{

		myBucket:{

			target:"myBucket",

			parameters:[{type:"string"}]

		}

	}

});

To use the S3 as a Dojo data store you can use the S3JsonRestStore module. First setup an RPC service 

as shown above and then pass the RPC service to the S3JsonRestStore:

dojo.require("dojox.data.S3JsonRestStore");

s3Store = new dojox.data.S3JsonRestStore({service:s3Buckets.myBucket}); // and create a store for it

You can then use the s3Store as a normal Read/Write Dojo Data store.
