    copied!<p>I am currently working with minification of JS files for improvement of page speed. I have been able to find the simplest method that works with almost all my js files in exception of two. The problem is with the js files for a wmd editor I am trying to implement to my site. The js files <code>wmd.js</code> and <code>showdown.js</code> are not being compressd and cache by the function in <code>scripts.php</code>. I checked with firebug tool, in the response header of <code>scripts.php</code> neither file is included in the final compressed js file.</p> <p>What is the issue with my process of compressing these js files(wmd &amp; showdown) and combining it into one? <a href="http://jachamboneth.cpsc3430.ausrc.org/wmdXss/default.php" rel="noreferrer">EXAMPLE SITE</a></p> <p><strong>js/scripts.php- takes care of compression and cache of js files</strong></p> <pre><code>&lt;?php error_reporting(E_ERROR); // see http://web.archive.org/web/20071211140719/http://www.w3.org/2005/MWI/BPWG/techs/CachingWithPhp // $lastModifiedDate must be a GMT Unix Timestamp // You can use gmmktime(...) to get such a timestamp // getlastmod() also provides this kind of timestamp for the last // modification date of the PHP file itself function cacheHeaders($lastModifiedDate) { if ($lastModifiedDate) { if (isset($_SERVER['HTTP_IF_MODIFIED_SINCE']) &amp;&amp; strtotime($_SERVER['HTTP_IF_MODIFIED_SINCE']) &gt;= $lastModifiedDate) { if (php_sapi_name()=='CGI') { Header("Status: 304 Not Modified"); } else { Header("HTTP/1.0 304 Not Modified"); } exit; } else { $gmtDate = gmdate("D, d M Y H:i:s \G\M\T",$lastModifiedDate); header('Last-Modified: '.$gmtDate); } } } // This function uses a static variable to track the most recent // last modification time function lastModificationTime($time=0) { static $last_mod ; if (!isset($last_mod) || $time &gt; $last_mod) { $last_mod = $time ; } return $last_mod ; } lastModificationTime(filemtime(__FILE__)); cacheHeaders(lastModificationTime()); header("Content-type: text/javascript; charset: UTF-8"); ob_start ("ob_gzhandler"); foreach (explode(",", $_GET['load']) as $value) { if (is_file("$value.js")) { $real_path = mb_strtolower(realpath("$value.js")); if (strpos($real_path, mb_strtolower(dirname(__FILE__))) !== false || strpos($real_path, mb_strtolower(dirname(dirname(__FILE__)).DIRECTORY_SEPARATOR.'modules'.DIRECTORY_SEPARATOR)) !== false) { lastModificationTime(filemtime("$value.js")); include("$value.js");echo "\n"; } } } ?&gt; </code></pre> <p><strong>The way i am calling the compressed.js</strong></p> <pre><code>&lt;script type = "text/javascript" src = "js/scripts.php?build=12345&amp;load=wmd,showdown"&gt;&lt;/script&gt; </code></pre>
