[users@httpd] Logging question - referer logging not working when done in addition to separate access_log

[Rose, John B]

Apache 2.2

We are attempting to set up a referer_log file. But when we add a CustomLog 
line specifically for the referer log it will not log,  if our CustomLog line 
for our access_log is there.

If we comment out the CustomLog line for access_log, then the CustomLog line 
for the referer_log logs correctly.

We also just removed the "env=!image-request", it still did not work

Can you tell us what we are doing wrong?  Httpd.conf code here ...

LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" 
combined
LogFormat "%h %l %u %t \"%r\" %>s %b" common
LogFormat "%{Referer}i -> %U" referer
LogFormat "%{User-agent}i" agent

...

   SetEnvIf Request_URI "\.(jpg)|(gif)|(png)|(css)|(js)$" onlylog
   SetEnvIf Request_URI "\.(jpg)|(gif)|(png)$" image-request
   CustomLog /apache/logs/access_log combined env=!image-request
   CustomLog /apache/logs/referer_log referer env=onlylog

Thanks
