I am trying to figure out if it is possible to force a page refresh for all users viewing a page at the same time.  I want all users to see a new page when one user submits info via a form.  I am picturing something along the lines of:

if(submit)
{
   write_to_file($POST[new info]);
   foreach($ip_addr in $ip_addr_list)
   {
     fsockopen($ip);
     fputs(headers to refresh page);
     fclose();
   }
}
else
{
   echo read_from_file();
}

My question is, can I send headers to an ip address and expect the web browser to refresh even though the user at that address hasn't done anything?
