mpm_common—A    set of  20  directives  common  to  all MPM modules

prefork—A   nonthreaded,    preforking  web server  that    works   much    like

to  earlier (1.3)   versions    of  Apache

worker—A    hybrid  multiprocess    multithreaded   server

MPM enables Apache to be used on equipment with fewer resources yet still
handle massive numbers of hits and provide stable service. The worker
module provides directives to control how many simultaneous connections
your server can handle.

NOTE

Other   MPMs    related to  other   platforms   are available   for Apache, such    as

mpm_netware for NetWare hosts   and mpm_winnt   for NT  platforms.  An

MPM named   perchild,   which   provides    user    ID  assignment  to  selected

daemon  processes,  is  under   development.    For more    information,    browse  to

the Apache  Software    Foundation’s    home    page,   at  www.apache.org.

Using .htaccess Configuration Files

Apache supports special configuration files, known as .htaccess files.
Almost any directive that appears in apache2.conf can appear in an
.htaccess file. This file, specified in the AccessFileName directive in
apache2.conf, sets configurations on a per-directory (usually in a user
directory) basis. As the system administrator, you can specify both the name
of this file and which of the server configurations can be overridden by the
contents of this file. This is especially useful for sites in which there are
multiple content providers and you want to control what these people can do
with their space.

To limit which server configurations the .htaccess files can override, use
the AllowOverride directive. AllowOverride can be set globally or
per directory. For example, in your apache2.conf file, you could use the
following:

Each directory to which Apache has access can be configured with

respect

to which services and features are allowed and/or disabled in that

directory (and its subdirectories).

First, we configure the "default" to be a very restrictive set of

permissions.
