Customizing Apache

I'm installing Apache from ports, and I want to know if there's a way to modify this part of the HTTP header:
Server: Apache/2.2.8 (FreeBSD)

Is it possible to modify what shows up? Thanks in advance.
You could add the following to your httpd.conf:
ServerTokens Prod
which will result in Apache only reporting: Server: Apache

You could also change the AP_SERVER_BASEPRODUCT in the source (src/include/httpd.h), but I would not recommend it, since some modules do a check on this (mod_perl will not want to compile if you do this for example).
