<h3>Sommaire</h3>

    <p>Ce module multi-processus (MPM) impl&#233;mente un serveur web bas&#233;
    exclusivement sur les threads et optimis&#233; pour Novell NetWare.</p>

    <p>Le thread ma&#238;tre est charg&#233; du lancement de threads esclaves qui
    attendent les connexions et les traitent au fur et &#224; mesure de leur
    arriv&#233;e. Le serveur HTTP Apache essaie toujours de maintenir
    plusieurs threads
    esclaves en <dfn>spare</dfn> (en r&#233;serve) ou inactifs. De cette
    fa&#231;on, les clients n'ont pas besoin d'attendre le lancement d'un
    nouveau thread enfant pour que leurs requ&#234;tes soient trait&#233;es.</p>

    <p>Les directives <code class="directive"><a href="../mod/mpm_common.html#startthreads">StartThreads</a></code>, <code class="directive"><a href="../mod/mpm_common.html#minsparethreads">MinSpareThreads</a></code>, <code class="directive"><a href="../mod/mpm_common.html#maxsparethreads">MaxSpareThreads</a></code>, et <code class="directive"><a href="#maxthreads">MaxThreads</a></code> contr&#244;lent
    la mani&#232;re dont le thread ma&#238;tre cr&#233;e les threads esclaves afin de
    traiter les requ&#234;tes. En g&#233;n&#233;ral, Apache httpd s'auto-r&#233;gule correctement,
    et la plupart des sites ne n&#233;cessitent aucune modification des
    valeurs par d&#233;faut de ces directives. Pour les sites dont le serveur
    est limit&#233; en m&#233;moire, il peut s'av&#233;rer n&#233;cessaire de diminuer la
    valeur de la directive <code class="directive"><a href="#maxthreads">MaxThreads</a></code> afin d'&#233;viter une
    hyper-activit&#233; du serveur (arr&#234;ts de threads inactifs et lancement incessant
    de nouveau threads). Vous trouverez plus d'informations &#224;
    propos du contr&#244;le de la cr&#233;ation de processus dans le document <a href="../misc/perf-tuning.html">conseils en mati&#232;re de
    performances</a>.</p>

    <p>La directive <code class="directive"><a href="../mod/mpm_common.html#maxrequestsperchild">MaxRequestsPerChild</a></code>
    contr&#244;le la fr&#233;quence &#224; laquelle le serveur recycle ses processus
    en arr&#234;tant les anciens et en en lan&#231;ant de nouveaux. Sous le
    syst&#232;me d'exploitation NetWare, il est vivement recommand&#233; de
    laisser cette directive &#224; 0, ce qui permet aux threads esclaves de
    continuer &#224; traiter les requ&#234;tes ind&#233;finiment.</p>

    <p>La directive <code class="directive">MaxThreads</code> d&#233;finit
    le nombre maximum de threads esclaves que l'on d&#233;sire autoriser. La

    compilation, la valeur de cette directive ne peut donc qu'&#234;tre
