of the httpd to determine how they should act.</p>
<p>An example can help to visualize the whole process. The following configuration uses the
<code class="directive"><a href="./mod/mod_headers.html#header">Header</a></code> directive of <code class="module"><a href="./mod/mod_headers.html">mod_headers</a></code> to set
- a specific HTTP header. What value will httpd set in the <code>foo</code> header for a request to
+ a specific HTTP header. What value will httpd set in the <code>CustomHeaderName</code> header for a request to
<code>/example/index.html</code> ?
</p>
<pre class="prettyprint lang-config"><Directory "/">
- Header set foo one
+ Header set CustomHeaderName one
<FilesMatch ".*">
- Header set foo three
+ Header set CustomHeaderName three
</FilesMatch>
</Directory>
<Directory "/example">
- Header set foo two
+ Header set CustomHeaderName two
</Directory></pre>
<ul>
- <li><code class="directive">Directory</code> "/" matches and an initial configuration to set the "foo" header with the value "one" is created.</li>
- <li><code class="directive">Directory</code> "/example" matches, and since <code class="module"><a href="./mod/mod_headers.html">mod_headers</a></code> specifies in its code to override in case of a merge, a new configuration is created to set the "foo" header with the value "two".</li>
- <li><code class="directive">FilesMatch</code> ".*" matches and another merge opportunity arises, causing the "foo" header
- to be set with the value "three".</li>
- <li>Eventually during the next steps of the HTTP request processing <code class="module"><a href="./mod/mod_headers.html">mod_headers</a></code> will be called and it will receive the configuration to set the "foo" header with the value "three". <code class="module"><a href="./mod/mod_headers.html">mod_headers</a></code> normally uses this configuration to perfom its job, namely setting the foo header. This does not mean that a module can't perform a more complex action like discarding directives because not needed or deprecated, etc..</li>

<p>This is true for .htaccess too since they have the same priority as <code class="directive">Directory</code> in the merge order. The important concept to understand is that configuration sections like <code class="directive">Directory</code> and <code class="directive">FilesMatch</code> are not comparable to module specific directives like <code class="directive"><a href="./mod/mod_headers.html#header">Header</a></code> or <code class="directive"><a href="./mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> because they operate on different levels.
