The HTTP protocol does provide a standard way to pass file metadata to the clients, but the server has to support it as well.
If this is a standard HTTP server, then you should be able to get the "File modified" timestamp from the "Last-Modified" HTTP header. However, there is no header that reflects the "File created" time. You need to modify the server to send the "File created" timestamp in a custom HTTP header.
