[Plugin: WP Super Cache] how to Combine external CSS

Good idea. Sorry about not doing that. Here’s what I had to do.

1) Since my server does not allow mod_deflate or mod_gzip, I had to compress the jsquery script with PHP. I created a file and placed it in my root directory called gzip.php. Within the file is this code:

<?php
ob_start (“ob_gzhandler”);
if( isset($_REQUEST[‘file’]) ){
$file = $_REQUEST[‘file’];
if( goodfile($file) ){
$ext = end(explode(“.”, $file));
switch($ext){
case ‘css’:$contenttype = ‘css’;break;
case ‘js’:$contenttype = ‘javascript’;break;
default:die();break;
}
header(‘Content-type: text/’.$contenttype.’; charset: UTF-8′);
header (“cache-control: must-revalidate”);
$offset = 60 * 60;
$expire = “expires: ” . gmdate (“D, d M Y H:i:s”, time() + $offset) . ” GMT”;
header ($expire);
$data = file_get_contents($file);
$data = compress($data);
echo $data;
}
}
exit;
function goodfile($file){
$invalidChars=array(“\\”,”\””,”;”,”>”,”<“,”.php”);
$file=str_replace($invalidChars,””,$file);
if( file_exists($file) ) return true;
return false;
}
function compress($buffer) {
$buffer = preg_replace(‘!/\*[^*]*\*+([^/][^*]*\*+)*/!’, ”, $buffer);
$buffer = str_replace(array(“\r\n”, “\r”, “\n”, “\t”, ‘ ‘, ‘ ‘, ‘ ‘), ”, $buffer);
return $buffer;
}
?>
I then added this to my .htaccess file:

RewriteEngine on
RewriteRule ^(.*).js$ pathtoyourwebsite/gzip.php?file=$1.js [L]
Now all my scripts are compressed. I still have not figured out how to combine the external scripts, but I am pleased with them all being compressed. Saves a lot of space. Hope this is helpful! Moreslides
