   First, this is client-side issue, and there is no way you can manage it
from a server. Different browsers just do it differently.

   Second, most browsers forget the form if you redirect to another page.

   Thired, such pages are not useless from user-friendliness - you confirm
that the info passed, so user can continu to work without worries.

   So, I recommend to redirect to "Thanks, the info added. Continue here >>>"
