>Description:
<http://www.apache.org/docs/mod/mod_log_config.html> says:

	" Beginning with Apache 1.3.5, the mod_log_config module has also
	subsumed the RefererIgnore functionality from _mod_log_referer_. The
	effect of RefererIgnore can be achieved by combinations of _SetEnvIf_ 
	directives and conditional CustomLog definitions.

and <http://www.apache.org/docs/mod/mod_setenvif.html> gives the example

		SetEnvIf Request_URI "\.(gif)|(jpg)|(xbm)$" object_is_image
		SetEnvIf Referer www\.mydomain\.com intra_site_referral
  

	The first will set the envariable object_is_image if the request was
	for an image file, and the second sets intra_site_referral if the 
	referring page was somewhere on the www.mydomain.com Web site.

This does NOT, however, simulate the behaviour of the RefererIgnore directive in
mod_log_referer.
>How-To-Repeat:

>Fix:
The "correct" construction, which reproduces the behaviour of

	RefererIgnore www.mydomain.com

is

	SetEnvIf Referer "^http://www\.mydomain\.com|www\.mydomain\.com" intra_site_referral
