<p>The <code class="directive"><a href="./mod/core.html#serveradmin">ServerAdmin</a></code> and
    <code class="directive"><a href="./mod/core.html#servertokens">ServerTokens</a></code> directives
    control what information about the server will be presented
    in server-generated documents such as error messages. The
    <code class="directive"><a href="./mod/core.html#servertokens">ServerTokens</a></code> directive
    sets the value of the Server HTTP response header field.</p>

<p>The <code class="directive"><a href="./mod/core.html#servername">ServerName</a></code>,
    <code class="directive"><a href="./mod/core.html#usecanonicalname">UseCanonicalName</a></code> and
    <code class="directive"><a href="./mod/core.html#usecanonicalphysicalport">UseCanonicalPhysicalPort</a></code>
    directives are used by the server to determine how to construct
    self-referential URLs. For example, when a client requests a
    directory, but does not include the trailing slash in the
    directory name, httpd must redirect the client to the full
    name including the trailing slash so that the client will
    correctly resolve relative references in the document.</p>

<p>These directives control the locations of the various files
    that httpd needs for proper operation. When the pathname used
    does not begin with a slash (/), the files are located relative
    to the <code class="directive"><a href="./mod/core.html#serverroot">ServerRoot</a></code>. Be careful
    about locating files in paths which are writable by non-root users.
    See the <a href="misc/security_tips.html#serverroot">security tips</a>
    documentation for more details.</p>

<p>The <code class="directive">LimitRequest</code>*
    directives are used to place limits on the amount of resources
    httpd will use in reading requests from clients. By limiting
    these values, some kinds of denial of service attacks can be
    mitigated.</p>

<p>The <code class="directive">RLimit</code>* directives
    are used to limit the amount of resources which can be used by
    processes forked off from the httpd children. In particular,
    this will control resources used by CGI scripts and SSI exec
    commands.</p>

<p>The <code class="directive"><a href="./mod/mpm_common.html#threadstacksize">ThreadStackSize</a></code>
    directive is used with some platforms to control the stack size.</p>

<h2 id="implementation">Implementation Choices <a title="Permanent link" href="#implementation" class="permalink">&para;</a></h2>

<p>The <code class="directive">Mutex</code> directive can be used to change
    the underlying implementation used for mutexes, in order to relieve
    functional or performance problems with <a class="glossarylink" href="./glossary.html#apr" title="see glossary">APR</a>'s
    default choice.</p>
