<div class="section">
<h2><a name="identification" id="identification">Identification du serveur</a></h2>
<table class="related"><tr><th>Modules Apparent�s</th><th>Directives Apparent�es</th></tr><tr><td /><td><ul><li><code class="directive"><a href="./mod/core.html#servername">ServerName</a></code></li><li><code class="directive"><a href="./mod/core.html#serveradmin">ServerAdmin</a></code></li><li><code class="directive"><a href="./mod/core.html#serversignature">ServerSignature</a></code></li><li><code class="directive"><a href="./mod/core.html#servertokens">ServerTokens</a></code></li><li><code class="directive"><a href="./mod/core.html#usecanonicalname">UseCanonicalName</a></code></li><li><code class="directive"><a href="./mod/core.html#usecanonicalphysicalport">UseCanonicalPhysicalPort</a></code></li></ul></td></tr></table>
<p>Les directives <code class="directive"><a href="./mod/core.html#serveradmin">ServerAdmin</a></code> et
<code class="directive"><a href="./mod/core.html#servertokens">ServerTokens</a></code> contr�lent la nature des
informations � propos du serveur qui seront affich�es dans les documents
g�n�r�s par le serveur comme les messages d'erreur. La directive
<code class="directive"><a href="./mod/core.html#servertokens">ServerTokens</a></code> d�finit la valeur du
champ d'en-t�te de la r�ponse du serveur HTTP.</p>
<p>Le serveur utilise les directives
<code class="directive"><a href="./mod/core.html#servername">ServerName</a></code>,
<code class="directive"><a href="./mod/core.html#usecanonicalname">UseCanonicalName</a></code> et
<code class="directive"><a href="./mod/core.html#usecanonicalphysicalport">UseCanonicalPhysicalPort</a></code> pour
d�terminer la mani�re de construire des URLs vers ses propres ressources.
Par exemple, quand un client �met une requ�te vers un r�pertoire, mais
n'ajoute pas le slash final au nom du r�pertoire, httpd doit rediriger le
client vers le nom complet incluant le slash final afin que le client
puisse r�soudre correctement les r�f�rences relatives pr�sentes dans
le document.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="./images/up.gif" /></a></div>
<div class="section">
<h2><a name="locations" id="locations">Localisation des fichiers</a></h2>
<table class="related"><tr><th>Modules Apparent�s</th><th>Directives Apparent�es</th></tr><tr><td /><td><ul><li><code class="directive"><a href="./mod/mpm_common.html#coredumpdirectory">CoreDumpDirectory</a></code></li><li><code class="directive"><a href="./mod/core.html#documentroot">DocumentRoot</a></code></li><li><code class="directive"><a href="./mod/core.html#errorlog">ErrorLog</a></code></li><li><code class="directive"><a href="./mod/core.html#mutex">Mutex</a></code></li><li><code class="directive"><a href="./mod/mpm_common.html#pidfile">PidFile</a></code></li><li><code class="directive"><a href="./mod/mpm_common.html#scoreboardfile">ScoreBoardFile</a></code></li><li><code class="directive"><a href="./mod/core.html#serverroot">ServerRoot</a></code></li></ul></td></tr></table>
<p>Ces directives contr�lent la localisation des diff�rents fichiers
n�cessaires au bon fonctionnement de httpd. Quand le chemin utilis� ne
commence pas par un slash (/), la localisation des fichiers est relative
� la valeur de la directive
<code class="directive"><a href="./mod/core.html#serverroot">ServerRoot</a></code>. Soyez prudent avec la
localisation de fichiers dans des r�pertoires o� les utilisateurs non root
ont les droits en �criture. Voir la documention sur les
<a href="misc/security_tips.html#serverroot">Conseils � propos
de la s�curit�</a> pour plus de d�tails.</p>

<h2><a name="resource" id="resource">Limitation de l'utilisation des ressources</a></h2>

<p>Les directives <code class="directive">LimitRequest</code>* permettent de
limiter la quantit� de ressources consomm�es par httpd pour le traitement
des requ�tes des clients. Cette limitation permet de minimiser les effets
de certains types d'attaques par d�ni de service.</p>
<p>Les directives <code class="directive">RLimit</code>* permettent de limiter la
quantit� de ressources utilisable par les processus initi�s (forked) par
les processus enfants httpd. Elles permettent en particulier de contr�ler
les ressources utilis�es par les scripts CGI et les commandes exec des
"Inclusions c�t� serveur" (Server Side Includes ou SSI).</p>
<p>La directive <code class="directive"><a href="./mod/mpm_common.html#threadstacksize">ThreadStackSize</a></code>
permet sur certaines plates-formes de contr�ler la taille de la pile.</p>
