Hello. In the HTTP protocol the webserver has no authorization to perform any action. It does only answer browsers requests. All this super interactive websites works this way, always using GET and/or POST methods. That is why Java script exists, it turns on the possibility to browsers perform advanced actions in order to generally improve user experience.
If you want a peace of page that auto refreshes, it must be achieved by GET and POST requests through a java script on the command. I'd suggest you to read a good HTML+Ajax book.
