+<p>
+The compress handler performs on-the-fly compression - it compresses the contents of an HTTP response as it is being sent, if the client indicates itself to be capable of decompressing the response transparently with the use of <a href="https://tools.ietf.org/html/rfc7231#section-5.3.4"><code>Accept-Encoding</code></a> header</li>, and if the response is deemed compressible according to the following rules.
+</p>
+<p>
+If <code>x-compress-hint</code> response header does not exist or the value is <code>auto</code>, then whether if the response is considered compressible depends on the <code>is_compressible</code> attribute assigned to the content type (see <a href="configure/file_directives.html#file.mime.addtypes"><code>file.mime.addtypes</code></a>).
+If <code>x-compress-hint</code> response header exists and the value is <code>on</code>, the response is always considered to be compressible.
+If the value of the response header is set to <code>off</code>, then the response never gets compressed.
+</p>
+
+<p>
+The following are the  configuration directives recognized by the handler.

+If the argument is <code>OFF</code>, on-the-fly compression is disabled.
+If the argument is a sequence, the elements are the list of compression algorithms to be enabled.
+If the argument is a mapping, each key specifies the compression algorithm to be enabled, and the values specify the quality of the algorithms.
+</p>
+<p>
+When both brotli and gzip are enabled and if the client supports both, H2O is hard-coded to prefer brotli.
