<h3>Sommaire</h3>


<p>Ce module fournit un filtre <code>RATE_LIMIT</code> pour limiter la
bande passante des clients. Cette contrainte s'applique &agrave; chaque r&eacute;ponse HTTP au
moment o&ugrave; elle est envoy&eacute;e au client ; elle n'affecte pas les autres &eacute;changes
entre le client et le serveur. La variable d'environnement
<code>rate-limit</code> permet de sp&eacute;cifier, en kb/s, le d&eacute;bit de la
connexion &agrave; simuler.</p>

<p>Optionnellement, il est possible, via la variable d'environnement
<code>rate-initial-burst</code>, de d&eacute;finir une quantit&eacute; de donn&eacute;es en
kOctets &agrave; transmettre &agrave; pleine vitesse avant de limiter la bande passante &agrave; la
valeur voulue.</p>

<div class="example"><h3>Exemple de configuration</h3><pre class="prettyprint lang-config">&lt;Location "/downloads"&gt;
    SetOutputFilter RATE_LIMIT
    SetEnv rate-limit 400
    SetEnv rate-initial-burst 512
&lt;/Location&gt;</pre>
<div class="warning">
Si la valeur affect&eacute;e &agrave; <code>rate-limit</code> d&eacute;passe la valeur maximale &agrave;
affecter &agrave; un entier, la limitation de bande passante sera d&eacute;sactiv&eacute;e. Si la
valeur affect&eacute;e &agrave; <code>rate-limit-burst</code> d&eacute;passe la valeur maximale &agrave;
affecter &agrave; un entier, la transmission du burst initial sans limitation de bande
passante sera d&eacute;sactiv&eacute;e.
