  36 <h3>Summary</h3>
  37
  38 <p>It is a module that sends static content at a bandwidth rate limit, defined
  39 by the various old modem standards. So, you can browse your site with a 56k
  40 V.92 modem, by adding something like this:</p>
  41
  42 <pre class="prettyprint lang-config">&lt;Location "/mysite"&gt;
  43     ModemStandard "V.92"
  44 &lt;/Location&gt;</pre>
  45
  46
  47 <p>Previously to do bandwidth rate limiting modules would have to block an entire
  48 thread, for each client, and insert sleeps to slow the bandwidth down.
  49 Using the new suspend feature, a handler can get callback N milliseconds in
  50 the future, and it will be invoked by the Event MPM on a different thread,
  51 once the timer hits.  From there the handler can continue to send data to the client.</p>
