想象一下，您的服务器不支持Apache上的deflate和gzip模块。 在这种情况下，有几种方法可以压缩数据。
我使用Apache重写模块和php gzip扩展来执行此操作。
我创建了一个名为gzip.php的文件来获取$ _SERVER ['REQUEST_URI']，获取其内容，设置标题，压缩和刷新内容作为文件。
我保留了所有文件的扩展名，因此apache保留了文件类型。
我将这些行添加到.htaccess：
RewriteEngine On RewriteCond %{REQUEST_FILENAME} -s RewriteRule ^((.*)\.(js|css))$ gzip.php [L] RewriteCond %{REQUEST_FILENAME} -s [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^.*$ index.php [NC,L]我已将这些标题添加到我的文件中：
$src = $_SERVER['REQUEST_URI']; // seconds, minutes, hours, days $expires = 60*60*24*14; ob_start(); ob_implicit_flush(0); header("Pragma: public"); header("Cache-Control: maxage=".$expires); header('Expires: ' . gmdate('D, d M Y H:i:s', time()+$expires) . ' GMT'); // Then do everything you want to do on the page $path = PUBLIC_DIR . $src; $info = pathinfo($path); $ext = strtolower($info['extension']); include_once 'Entezar/File.php'; $mimeType = Entezar_File::getMimeType($path); header("Content-type: $mimeType"); if (file_exists($path) && in_array($ext, array('js', 'css'))) { $fs = stat($path); header("Etag: ".sprintf('"%x-%x-%s"', $fs['ino'], $fs['size'],base_convert(str_pad($fs['mtime'],16,"0"),10,16))); echo file_get_contents($path); } unset($path, $src, $info, $ext);我的问题是，当我在php中使用apache重写模块来压缩内容时，FireFox根本不会从缓存中加载我的文件（css或js）！ 有谁能够帮助我？！
Imagine that your server does not support deflate and gzip module on Apache. In this case there are several ways to compress your data.
I use the Apache rewrite module and php gzip extension to do this.
I created one file named gzip.php to get $_SERVER['REQUEST_URI'], get its content, set headers, compress and flush content as a file.
I kept the extension of all files so apache preserves the file types.
I added these lines to .htaccess:
RewriteEngine On RewriteCond %{REQUEST_FILENAME} -s RewriteRule ^((.*)\.(js|css))$ gzip.php [L] RewriteCond %{REQUEST_FILENAME} -s [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^.*$ index.php [NC,L]I've added these headers to my files:
$src = $_SERVER['REQUEST_URI']; // seconds, minutes, hours, days $expires = 60*60*24*14; ob_start(); ob_implicit_flush(0); header("Pragma: public"); header("Cache-Control: maxage=".$expires); header('Expires: ' . gmdate('D, d M Y H:i:s', time()+$expires) . ' GMT'); // Then do everything you want to do on the page $path = PUBLIC_DIR . $src; $info = pathinfo($path); $ext = strtolower($info['extension']); include_once 'Entezar/File.php'; $mimeType = Entezar_File::getMimeType($path); header("Content-type: $mimeType"); if (file_exists($path) && in_array($ext, array('js', 'css'))) { $fs = stat($path); header("Etag: ".sprintf('"%x-%x-%s"', $fs['ino'], $fs['size'],base_convert(str_pad($fs['mtime'],16,"0"),10,16))); echo file_get_contents($path); } unset($path, $src, $info, $ext);My problem is that when I use apache rewrite module along php with to compress contents, FireFox does not load my files (css or js) from the cache at all! Can anybody help me?!

Digger的Finder！ 在做任何工作（压缩gzip.php文件中的一些文件）之前，你应该检查$ _SERVER变量中的这两个键（当然你应该在某个地方设置expiration和cache headers，比如apache .htaccess文件或其他地方......）：
$etag = '"' . md5($contents) . '"'; $etag_header = 'Etag: ' . $etag; header($etag_header); if (isset($_SERVER['HTTP_IF_NONE_MATCH']) and $_SERVER['HTTP_IF_NONE_MATCH']==$etag) { header("HTTP/1.1 304 Not Modified"); exit(); }在apache .htaccess中添加以下行：
<ifModule mod_expires.c> ExpiresActive On ExpiresDefault "access plus 1 seconds" ExpiresByType text/html "access plus 1 seconds" ExpiresByType image/gif "access plus 2592000 seconds" ExpiresByType image/jpeg "access plus 2592000 seconds" ExpiresByType image/png "access plus 2592000 seconds" ExpiresByType text/css "access plus 604800 seconds" ExpiresByType text/javascript "access plus 216000 seconds" ExpiresByType application/x-javascript "access plus 216000 seconds" </ifModule> <ifModule mod_headers.c> <filesMatch "\\.(ico|pdf|flv|jpg|jpeg|png|gif|swf)$"> Header set Cache-Control "max-age=2592000, public" </filesMatch> <filesMatch "\\.(css)$"> Header set Cache-Control "max-age=604800, public" </filesMatch> <filesMatch "\\.(js)$"> Header set Cache-Control "max-age=216000, private" </filesMatch> <filesMatch "\\.(xml|txt)$"> Header set Cache-Control "max-age=216000, public, must-revalidate" </filesMatch> <filesMatch "\\.(html|htm|php)$"> Header set Cache-Control "max-age=1, private, must-revalidate" </filesMatch> </ifModule>Digger's Finder! Before doing any work(compress some files in gzip.php file) you should check these two keys in $_SERVER variable(Of course you should set expiration and cache headers in somewhere such as apache .htaccess file or other place... ):
$etag = '"' . md5($contents) . '"'; $etag_header = 'Etag: ' . $etag; header($etag_header); if (isset($_SERVER['HTTP_IF_NONE_MATCH']) and $_SERVER['HTTP_IF_NONE_MATCH']==$etag) { header("HTTP/1.1 304 Not Modified"); exit(); }In apache .htaccess add these lines:
<ifModule mod_expires.c> ExpiresActive On ExpiresDefault "access plus 1 seconds" ExpiresByType text/html "access plus 1 seconds" ExpiresByType image/gif "access plus 2592000 seconds" ExpiresByType image/jpeg "access plus 2592000 seconds" ExpiresByType image/png "access plus 2592000 seconds" ExpiresByType text/css "access plus 604800 seconds" ExpiresByType text/javascript "access plus 216000 seconds" ExpiresByType application/x-javascript "access plus 216000 seconds" </ifModule> <ifModule mod_headers.c> <filesMatch "\\.(ico|pdf|flv|jpg|jpeg|png|gif|swf)$"> Header set Cache-Control "max-age=2592000, public" </filesMatch> <filesMatch "\\.(css)$"> Header set Cache-Control "max-age=604800, public" </filesMatch> <filesMatch "\\.(js)$"> Header set Cache-Control "max-age=216000, private" </filesMatch> <filesMatch "\\.(xml|txt)$"> Header set Cache-Control "max-age=216000, public, must-revalidate" </filesMatch> <filesMatch "\\.(html|htm|php)$"> Header set Cache-Control "max-age=1, private, must-revalidate" </filesMatch> </ifModule>更多推荐
