thanks keith, that was the general approach i used in the end.

actually the system has a navigation frame, so what i did was just provide 
a "switch user" link to the front page, targetting the content frame.

actually actually, i didn't like the way the new login box defaulted the 
username to "dummy" (or whatever was in the link) and the cursor sitting in 
the password field.  so I used onClick="changeUser()" on the link with the 

  username = 'enter username';

  function changeUser() {
         newusername = prompt('Username:','');

         document.all.changeuseranchor = 'http://' + newusername + 
':dummy at prometheus.saturn.co.nz/noc-cgi/overview.cgi';
         document.all.changeuseranchor.target = 'canvas';


this gives two prompts - first a JS one to get the username, then the real 
login box.  a bit of a hack, but hey.

next question:  does anyone know how to retrieve the HTTP authent username 
with JS? i can't find it in the API.  just so i can display the current 
username in that nav frame without the nav having to be a CGI (too slow).
