apache2.conf

Sets the default security model of the Apache2 HTTPD server. It does

not allow access to the root filesystem outside of /usr/share and /var/www.

The former is used by web applications packaged in Debian,

the latter may be used for local directories served by the web server. If

your system is serving content from a sub-directory in /srv you must allow

access here, or in any related virtual host.

AccessFileName: The name of the file to look for in each directory

for additional configuration directives. See also the AllowOverride

directive.

AccessFileName .htaccess

The following lines prevent .htaccess and .htpasswd files from being

viewed by Web clients.

    Require all denied

The following directives define some format nicknames for use with

a CustomLog directive.

These deviate from the Common Log Format definitions in that they use %O

(the actual bytes sent including headers) instead of %b (the size of the

requested file), because the latter makes it impossible to detect partial

requests.

Note that the use of %{X-Forwarded-For}i instead of %h is not recommended.

Use mod_remoteip instead.

LogFormat "%v:%p %h %l %u %t "%r" %>s %O "%{Referer}i" "%{User-Agent}i"" vhost_combined
LogFormat "%h %l %u %t "%r" %>s %O "%{Referer}i" "%{User-Agent}i"" combined
LogFormat "%h %l %u %t "%r" %>s %O" common
LogFormat "%{Referer}i -> %U" referer
LogFormat "%{User-agent}i" agent
