AJAM!!! lo hago a propósito, para que algunos navegadores como Chrome u Opera no me cacheén las páginas y poder cargar contenido dinámico desde el servidor
http://www.funcion13.com/2012/04/19/...jax-de-jquery/
utilizo una variable aleatoria 'random' que puede verse en las peticiones _GET
Si, eso está perfecto para tus php, pero para los botoncitos, no lo hacés, ni hace falta.
