=46ield wasn't really the term I wanted.

HTTP_REFERER is a header which some browsers send (including Netscape,
although last time I checked, it doesn't send it on reloads) indicating the
page that they were at before the current one.  It's passed via the CGI
interface.  So a CGI script can use it to implement a back button.   I
would advise, however, that if you use it, you only use it if "Back" goes
back to another page on your site.  It would feel pretty odd if pressing
"Back" on your page took me to another organizations web site entirely.

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
