Requesting for the page and refresh has no distinction at the server.

Back button mostly function from browser proxy, if not then it is also the same as sending a request.

Yeah, but for multiple submit, like if user press a button multiple times, there is a way to control that.

Another possibility would be to use the synchronizer token pattern.

Basically you issue a "token identifier" to each page, so you can detect duplicate submissions/refreshes.
