You know how if a web server can't find a requested file (or some other error), it'll just spill its beans about what kinds of modules, their versions, the web server, and the os on top of which it's running?
How do I disable that? What config files do I need to change? I swear, I googled for it but came up short. I even tried grepping for parts of the banner in the /etc/apache2 dirrectory without success. I don't know, maybe it's just too early for me

Haven't had coffee yet.
