How to explicitly set checkbox unchecked

Question

I have a xhtml page with transitional doctype having a checkbox that I want to be unchecked after loading. No JavaScript! In Firefox 3.5 (for instance, there may be other browsers) user can check input, than reload page and get input checked. How can I overcome this behaviour?

Answer 1

Use

autocomplete="off"

Also have a look at Why does the checkbox stay checked when reloading the page?
