### Domain

By default, MinIO supports path-style requests that are of the format <http://mydomain.com/bucket/object>. `MINIO_DOMAIN` environment variable is used to enable virtual-host-style requests. If the request `Host` header matches with `(.+).mydomain.com` then the matched pattern `$1` is used as bucket and the path is used as object. Read more about path-style and virtual-host-style [here](http://docs.aws.amazon.com/AmazonS3/latest/dev/RESTAPI.html).

	if len(domains) == 0 {
		return path, nil
	}

	// If virtual-host-style is enabled construct the "resource" properly.
	xhost, err := xnet.ParseHost(host)
	if err != nil {

// IsPCFTile returns if server is running in PCF
func IsPCFTile() bool {
	return env.Get("MINIO_PCF_TILE_VERSION", "") != ""
}

// DO NOT CHANGE USER AGENT STYLE.
// The style should be
//
//	MinIO (<OS>; <ARCH>[; <MODE>][; dcos][; kubernetes][; docker][; source]) MinIO/<VERSION> MinIO/<RELEASE-TAG> MinIO/<COMMIT-ID> [MinIO/universe-<PACKAGE-NAME>] [MinIO/helm-<HELM-VERSION>]
//

2. The id_token self-contains the authorization information in a manner that can be verified. For example, by encoding authorization information along with a signature into the token.

WSO2 generates tokens in first style by default, but if to be used with MinIO we should configure WSO2 to provide JWT tokens instead.

### 3. Generate Self-contained Access Tokens
