<h2 id="_name">Name</h2>
<p>cowboy_compress_h - Compress stream handler</p>
<h2 id="_description">Description</h2>
<p>The module <code>cowboy_compress_h</code> compresses response bodies automatically when the client supports it. It will not try to compress responses that already have a content encoding.</p>
<p>Normal responses will only be compressed when their size is lower than the configured threshold. Streamed responses are always compressed, including when the sendfile command is used. Because the file must be read in memory to be compressed, this module is <strong>not</strong> suitable for automatically compressing large files.</p>

<p>Configuration for the default stream handler.</p>
<p>The default value is given next to the option name:</p>
<dl><dt>compress_buffering (false)</dt>
<dd><p>Whether the output will be buffered. By default no buffering is done to provide maximum compatibility at the cost of a lower compression rate.</p>
</dd>
<dt>compress_threshold (300)</dt>
<dd><p>How large the response body must be to be compressed when the response isn't streamed.</p>
