Title: Apache2 header information clear/hide

Hi,

Is there any way to clear header information when I using ProxyPass and ProxyPassReverse?
Here is ngreped info:
T xxx.xxx.xxx.xxx:46087 -> xxx.xxx.xxx.xxx:80 [AP]
  GET / HTTP/1.1..Host: forwarded.domain..User-Agent: Mozilla/5.0 ..Accept-Language: en-us..Accept-Encoding: gzip, deflate..Authorization: Basic ..X-Forwarded-For: xxx.xxx.xxx.xxx.X-Forwarded-Host: orig.domain..X-Forwarded-Server: servername..Connection: Keep-Alive....                  

I would like to clear X-Forwarded-For, Forwarded-Host, X-Forwarded-Server. 
How can I do this?
Thanks,
Szabolcs
