    <p>Cette directive permet d'effectuer une optimisation de la socket
    d'coute d'un type de protocole en fonction du systme
    d'exploitation. Le but premier est de faire en sorte que le noyau
    n'envoie pas de socket au processus du serveur jusqu' ce que
    des donnes soient reues, ou qu'une requte HTTP complte soit mise
    en tampon. Seuls les <a href="http://www.freebsd.org/cgi/man.cgi?query=accept_filter&amp;     sektion=9">Filtres d'acceptation de FreeBSD</a>, le filtre plus
    primitif <code>TCP_DEFER_ACCEPT</code> sous Linux, et la version
    optimise d'AcceptEx() de Windows sont actuellement supports.</p>

    <p>L'utilisation de l'argument <code>none</code> va dsactiver tout
    filtre d'acceptation pour ce protocole. Ceci s'avre utile pour les
    protocoles qui ncessitent l'envoi de donnes par le serveur en
    premier, comme <code>ftp:</code> ou <code>nntp</code>:</p>
    <pre class="prettyprint lang-config">AcceptFilter nntp none</pre>


    <p>Les noms de protocoles par dfaut sont <code>https</code> pour le
    port 443 et <code>http</code> pour tous les autres ports. Pour
    spcifier un autre protocole  utiliser avec un port en coute,
    ajoutez l'argument <var>protocol</var>  la directive <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code>.</p>

    <p>Sous FreeBSD, les valeurs par dfaut sont :</p>
    <pre class="prettyprint lang-config">AcceptFilter http httpready
AcceptFilter https dataready</pre>


    <p>Le filtre d'acceptation <code>httpready</code> met en tampon des
    requtes HTTP entires au niveau du noyau. Quand une requte
    entire a t reue, le noyau l'envoie au serveur. Voir la page de
    manuel de <a href="http://www.freebsd.org/cgi/man.cgi?query=accf_http&amp;     sektion=9">accf_http(9)</a> pour plus de dtails. Comme les requtes
    HTTPS sont chiffres, celles-ci n'autorisent que le filtre <a href="http://www.freebsd.org/cgi/man.cgi?query=accf_data&amp;     sektion=9">accf_data(9)</a>.</p>

    <p>Sous Linux, les valeurs par dfaut sont :</p>
    <pre class="prettyprint lang-config">AcceptFilter http data
AcceptFilter https data</pre>


    <p>Le filtre <code>TCP_DEFER_ACCEPT</code> de Linux ne supporte pas
    la mise en tampon des requtes http. Toute valeur autre que
    <code>none</code> active le filtre <code>TCP_DEFER_ACCEPT</code>
    pour ce protocole. Pour plus de dtails, voir la page de
    manuel Linux de <a href="http://man7.org/linux/man-pages/man7/tcp.7.html">tcp(7)</a>.</p>

    <p>Sous Windows, les valeurs par dfaut sont :</p>
    <pre class="prettyprint lang-config">AcceptFilter http connect
AcceptFilter https connect</pre>


    <p>Le module MPM pour Windows mpm_winnt utilise la directive
    AcceptFilter comme commutateur de l'API AcceptEx(), et ne supporte
    pas la mise en tampon du protocole http. <code>connect</code>
    utilise l'API AcceptEx(), extrait aussi les adresses rseau finales,
    mais  l'instar de <code>none</code>, la valeur <code>connect</code>
    n'attend pas la transmission des donnes initiales.</p>

    <p>Sous Windows, <code>none</code> utilise accept() au lieu
    d'AcceptEx(), et ne recycle pas les sockets entre les connexions.
    Ceci s'avre utile pour les interfaces rseau dont le pilote est
