[users@httpd] Multiple domains in variable for "SetEnvIf Referer"

[Doug Strick <do...@gmail.com>]

I have a rewrite where we'll be creating a cookie if you're being
redirected from a few specific domains.  Is there a way I can use one
variable to handle multiple domains or does the rewrite block need to be
repeated based on the domain?  I'd like one block to be able to be directed
to handle 3-4 specific domains.  Thanks

SetEnvIf Referer test.com OLD_REFERER=$1
RewriteCond %{HTTP_REFERER} test.com [NC]
RewriteRule ^ - [CO=LEGACY:%{ENV:OLD_REFERER}:.example.com:1440:/]
