The "-" referer probably comes because the caller did not provide a 
"Referer:" header in his request.

For example, open a new browser and acces a URL on your server, then 
look at the access log.  It will probably show a "-" for the referer.

Or, if you have perl installed, re-do the example I sent earlier, but do 
not specify a "-H" switch.

Got it ?
The "referer" information in your access log *only* represents the 
content of the "Referer:" header sent by the client,  If there is none, 
then you get "-" for that field in the access log.
It is written so, so that if you have a program analysing your access 
log, it will not get confused because one line has fewer fields than the 
Brilliant, those Apache developers, no ?
