apache 的設定…

使用 apache 的人應該要把一些 msg 關掉，這樣對外的資訊就會少一點了…

#
# ServerTokens
# This directive configures what you return as the Server HTTP response Header. The default is ‘Full’ which sends information about the OS-Type and compiled in modules.
# Set to one of: Full | OS | Minor | Minimal | Major | Prod
# where Full conveys the most information, and Prod the least.
#
ServerTokens Prod

#
# Optionally add a line containing the server version and virtual host name to server-generated pages (internal error documents, FTP directory listings, mod_status and mod_info output etc., but not CGI generated documents or custom error documents). Set to “EMail” to also include a mailto: link to the ServerAdmin.
# Set to one of: On | Off | EMail
#
ServerSignature Off

然後跑看看 HEAD：
