several referer errors

[dbayly at udena.ch]

Why not have a look yourself. Here's a way that may make what is 
happening clearer.

Change the port that you are serving from to a non standard value; 
many proxies work on a certain port (typically 80)  and try the same 
page. This takes only a few minutes so you could even think of doing 
it on a live server.

If it is different then to see what is happening set 
user.webserver.prefs.fldebug to true and    compare the debug windows 
at system.temp.webserver.debugprefilter  for the two port values. The 
difference should be  detectable
