I'm having trouble developing a "Submit Once" form validation cookie.  The 
idea is when the user submits a form, a cookie would be placed on the 
user's pc which would prevent the user from resubmitting the form at any 
given time.  I would like the cookie to be created with the "onClick" 
function and expire within any set amount of time.  I understand the user 
can delete the cookie at anytime, but that is not a concern. 

Thanks
