<h3>Sommaire</h3>
<p>Ce module fournit un filtre <code>RATE_LIMIT</code> pour limiter la
bande passante des clients. Cette contrainte s'applique à chaque réponse HTTP au
moment où elle est envoyée au client ; elle n'affecte pas les autres échanges
entre le client et le serveur. La variable d'environnement
<code>rate-limit</code> permet de spécifier, en kb/s, le débit de la
connexion à simuler.</p>
<p>Optionnellement, il est possible, via la variable d'environnement
<code>rate-initial-burst</code>, de définir une quantité de données en
kOctets à transmettre à pleine vitesse avant de limiter la bande passante à 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 affectée à <code>rate-limit</code> dépasse la valeur maximale à
affecter à un entier, la limitation de bande passante sera désactivée. Si la
valeur affectée à <code>rate-limit-burst</code> dépasse la valeur maximale à
affecter à un entier, la transmission du burst initial sans limitation de bande
passante sera désactivée.
