<code class="directive"><a href="../mod/mod_setenvif.html#browsermatch">BrowserMatch</a></code> + ディレクティブで、推測したユーザーエージェントを修正します。 + なぜなら Microsoft Internet Explorer も "Mozilla/4" と特定されますが、 + これらは実際には圧縮を扱うことができるからです。 + <code>User-Agent</code> ヘッダを "MSIE" + (<code>\b</code> は「単語の境界」を意味します) の追加文字で検査して、 + これ以前に設定した制限を再び解除します。</p> + + <div class="note"><h3>注</h3> + <code>DEFLATE</code>
