This is broken.  magnus-internal is a content type used to trigger
internal behaviour in Netscape web servers, not to be returned to
the client.  This is probably a Netscape bug, rather than a content
provider bug.

The most common reason for insisting on Referer now is probably not
click trailing, but to prevent outside sites cashing in on your site
by linking to your forms.  It can also be used as a weak backup to
security by obscurity access control schemes.

Note that scripted use of Lynx would almost certainly violate the
reasons for insisting that you access from within the site, as it
is almost certain that human user will never see the adverts, so 
I cannot expect any sympathy for requests to relax commercially 
imposed insistance on Referer if any automation is involved, or
you are using a bookmark to bypass pages.
