I am working on setting an HTTP header field inside HTTP form using [Accept-Language] filed.

I can read its value from a JSP file that is junctioned to that HTML form, yet the HTML form set that field with the browser/machine language local that is in my case is [en-us].

I need to know the HTML synatx format pf writing [Accept-Language] with a cutomized static value inside HTML?

I need a javascript code or url that tells how to send that [Accept-Language] field in a customized manner to the JSP?
