I don't think this can work, if BlockBrowser=1 then you set GoAway,  
if BlockReferer=1 then you set GoAway. If I deny from env=GoAway,  
then I deny from BlockBrowser OR from BlockReferer. I want to deny  
only if both BlockBrowser AND BlockReferer are set.

But you give me an idea to work with. I'm going to try:

SetEnv GoAway 1
BrowserMatch !"^$" !GoAway
SetEnvIf Referer !"^$" !GoAway
Deny from env=GoAway

So, if I'm correct, GoAway is set, then if BrowserMatch is good  
GoAway is unset, if SetEnvIf Referer is good GoAway is unset, is  
GoAway is still set, the deny is triggered.

Does it look ok ?
