Cleanup cache before start form [duplicate]

  forms, html, php

i made a form with a few inputs. One input named voornaam (forname) and one called achternaam (surname).

<input type="text" name="voornaam">

Sorry for the dutch.
Now other forms (other websites ) also uses these names in there forms. And the browser remembers what the input was in these forms. How can i get a clean start with my form. So it does not use the others forms input.
Please do not tell me my users need to clean up there cash. 🙂
