<dl>
<dt>Authentication and Authorization</dt>
<dd>
<p>Authentication is any process by which you verify that
someone is who they claim they are. Authorization is any
process by which someone is allowed to be where they want to
go, or to have information that they want to have.</p>
<p>See: <a href="auth.html">Authentication, Authorization</a></p>
</dd>
</dl>
<dl>
<dt>Access Control</dt>
<dd>
<p>Access control refers to the process of restricting, or
granting access to a resource based on arbitrary criteria. There
are a variety of different ways that this can be
accomplished.</p>
<p>See: <a href="access.html">Access Control</a></p>
</dd>
</dl>
<dl>
<dt>Dynamic Content with CGI</dt>
<dd>
<p>The CGI (Common Gateway Interface) defines a way for a web
server to interact with external content-generating programs,
which are often referred to as CGI programs or CGI scripts. It
is a simple way to put dynamic content on
your web site. This document will be an introduction to setting
up CGI on your Apache web server, and getting started writing
CGI programs.</p>
<p>See: <a href="cgi.html">CGI: Dynamic Content</a></p>
</dd>
</dl>
<dl>
<dt><code>.htaccess</code> files</dt>
<dd>
<p><code>.htaccess</code> files provide a way to make configuration
changes on a per-directory basis. A file, containing one or more
configuration directives, is placed in a particular document directory,
and the directives apply to that directory, and all subdirectories thereof.</p>
<p>See: <a href="htaccess.html"><code>.htaccess</code> files</a></p>
</dd>
</dl>
<dl>
<dt>HTTP/2 with httpd</dt>
<dd>
<p>HTTP/2 is the evolution of the world's most successful application layer protocol, HTTP.
It focuses on making more efficient use of network resources without changing the semantics of HTTP.
This guide explains how HTTP/2 is implemented in httpd, showing basic configurations tips and
best practices.
</p>
<p>See: <a href="http2.html">HTTP/2 guide</a></p>
</dd>
</dl>
<dl>
<dt>Introduction to Server Side Includes</dt>
<dd>
<p>SSI (Server Side Includes) are directives that are placed in
HTML pages, and evaluated on the server while the pages are
being served. They let you add dynamically generated content to
an existing HTML page, without having to serve the entire page
via a CGI program, or other dynamic technology.</p>
<p>See: <a href="ssi.html">Server Side Includes (SSI)</a></p>
</dd>
</dl>
<dl>
<dt>Per-user web directories</dt>
<dd>
<p>On systems with multiple users, each user can be permitted to have a
web site in their home directory using the <code class="directive"><a href="../mod/mod_userdir.html#userdir">UserDir</a></code> directive. Visitors
to a URL <code>http://example.com/~username/</code> will get content
out of the home directory of the user "<code>username</code>", out of
the subdirectory specified by the <code class="directive"><a href="../mod/mod_userdir.html#userdir">UserDir</a></code> directive.</p>
<p>See: <a href="public_html.html">User web directories (<code>public_html</code>)</a></p>
</dd>
</dl>
<dl>
<dt>Reverse Proxy guide</dt>
<dd>
<p>Apache httpd has extensive capabilities as a reverse proxy server using the
<code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code> directive as well as
<code class="directive"><a href="../mod/mod_proxy.html#balancermember">BalancerMember</a></code> to create sophisticated
reverse proxying implementations which provide for high-availability, load
balancing and failover, cloud-based clustering and dynamic on-the-fly reconfiguration.</p>
<p>See: <a href="reverse_proxy.html">Reverse proxy guide</a></p>
</dd>
</dl>
<dl>
<dt>Rewriting URLs with mod_rewrite</dt>
<dd>
<p>Rewriting URLs with (and without)
<code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> tends to be one of the most
frequently asked topics on our mailing lists and IRC channels.
We have devoted <a href="../rewrite/">and entire section of our
documentation</a> to howtos and recipes around this topic.</p>
