AddMetadata Method
Adds a metadata item to the Metadata properties.
procedure AddMetadata(Name: String; Value: String);
Remarks
This method adds a metadata item to the Metadata* properties. Name specifies the name of the item, and Value specifies the value of the item. Keep in mind that the server stores metadata names in lowercase.
If Name begins with a service-specific metadata (e.g., x-amz-meta-, x-goog-meta-, etc.), it will be stripped off. The component will take care of prepending it when sending metadata to the server.
