you have used "post" method ( which you are supose to ). browsers behave like this.
and if you don't want to see the warning page use "GET" method. u will not see the warning now. aside with that your boss will not like the new solution as it will append the complete query in address bar ,
let him know what you did is fine. and browser behaving in expected manner.
