[Javascript] Slightly OT: Auto re-fill of form elements on browser Back button.

[Hakan M (Backbase)]

Greetings.

As most of you probably experienced at one point or another, browsers 
tend to keep the filled in values of form elements if you submit the 
form and then hit the Back-button to go back to the form again. This 
might be convenient in most cases, but I need to be able to control 
this, and reset the values to their default values whenever the form is 
"reloaded" in any way.

My questions is; Do anybody know of the exact criteria for this 
auto-refill to happen? Is it only when you go back or is it simply a 
question of caching on the browsers behalf?

Turning the feature off through the browser or sending HTTP-headers to 
prevent caching is not really an option, I'm afraid.

Thankful for any suggestions.

Regards,
H
