[users@httpd] Logging Denied Referrers

[Grant Peel]

Hi all,

As mentioned in previous emails, I am trying to deny access via SetEnvIf 
statements in my httpd.conf (to block smap bots / email harvesters etc.

I have two questions:

1. My server has several hundred VirtualHost directives. When the SetEnvIf 
statements are just placed in the main server config, will the block those 
referrers from the VirtualHosts as well?

2. How can I set logging to see if SetEnvIf statements are doing what I 
intended them to do?
