I can add custom headers through a PHP script, but nothing globally, sadly. I'm going to try experimenting with GZip headers and some PHP to try and get it to serve some statically gzipped goodness.Wladimir Palant wrote:Does your host allow you to add a custom header? Then you could use statically gzipped files and only add a header to indicate that the browser has to uncompress them (Dr.Evil's list uses this solution). Problem with other solutions is: Firefox cannot uncompress ZIP files on the fly, one would need temporary files. And GZIP uncompressor is not exposed to extensions as far as I can see.
Well I've always seen that some of the other lists were smaller (file size wise) and always figured that my list was huge! But then common sense kicked in and I realised that everyone was using GZipping... but me! lolfanboy wrote:your list getting a bit big there jamie?
Code: Select all
type subscription_latest.txt | gzip -9 -f > subscription_latest.gzCode: Select all
<?php
if(substr_count($_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip'))
{
global $HTTP_ACCEPT_ENCODING;
if( headers_sent() ){
$encoding = false;
}elseif( strpos($HTTP_ACCEPT_ENCODING, 'x-gzip') !== false ){
$encoding = 'x-gzip';

$encoding = 'gzip';

// Path to your normal (uncompressed) list
include_once("subscription.php");
}
?>
Now to move this live and start optimizing the list.Again it comes down to the host, it's a bad performance hit yes, but nowhere near as bad as Gzipping on demand, and caters to the fact that some hosts (including mine) seem to ignore .htaccess files completelyWladimir Palant wrote:Last I heard, serving files through PHP was extremely bad performance-wise. So it is much better if you have Apache with mod_header and can use .htaccess.
Code: Select all
<?php
// Variables
$text_file = 'subscription_file.txt';
$gmt_mtime = gmdate('D, d M Y H:i:s', filemtime($text_file)).' GMT';
$expires = gmdate('D, d M Y H:i:s', strtotime('+5 days')).' GMT';
// Code
if($_SERVER['HTTP_IF_MODIFIED_SINCE'] == $gmt_mtime){
header('Expires: '.$expires);
header('HTTP/1.0 304 Not Modified');
exit();
}
ob_start("ob_gzhandler");
header('Last-Modified: '.$gmt_mtime);
header('Expires: '.$expires);
header('Content-Type: text/plain; charset=UTF-8');
include($text_file);
?>That's exactly what I did with that codechewey wrote:Jamie: Why not put the compressed list on your server and let the server deliver it as gzipped?
My list is compressed exactly once per revision: On my machine before being transferred to the server.
Presto: No performance hit at all.
I gzip it locally (highest compression posssible) and then upload it, I have a nice automated script to download the un-gzipped list, compress it, and then upload it via FTP, works like a charm. Then the script just loads the .gz file and displays it with just a single header inserted above it. Similar to the mod_rewrite mods that people do, just through the power of PHP
