MULTIPLE cookieless domains (speed improvement)

by LuisManson 10 Jul 2010

Since vbulletin uses a LOT of images plus CSS and JS i decided to separate all of them into cookie less domains

First of all on admincp set cookies only for your forum MAIN domain (ie www.mysite.com) not .mysite.com

DNS:
First of all i created some subdomains
static.mysite.com
static2.mysite.com
staticcss.mysite.com
staticjs.mysite.com

all of them pointing to the same server

Web server:
i created a new vhost:

Code:

<VirtualHost *:80>
    ServerAdmin email"
    DocumentRoot "/usr/local/www/estaticos_mysite_com"
    ServerName static.mysite.com
    ServerAlias static2.mysite.com staticcss.mysite.com staticjs.mysite.com
    ErrorLog "/var/log/www/mysite-error.log"
    CustomLog "/var/log/www/mysite-access.log" combined
    Alias /images /usr/local/www/web_mysite_com/images
    Alias /clientscript /usr/local/www/web_mysite_com/clientscript
</VirtualHost>

Filesystem:
My vb site is in: /usr/local/www/web_mysite_com
and the static content is in: /usr/local/www/estaticos_mysite_com
inside this new vhost directory i also made two aliases (because of my permissions)

clientscript -> ../web_mysite_com/clientscript
images -> ../web_mysite_com/images

* given my permission direct access to this shite would give you a forbidden, maybe you could create an empty index file

htaccess:
i have a redirect for my domain so now i had to make a few changes to:

Code:

RewriteCond %{HTTP_HOST} !^www\.mysite\.com
RewriteCond %{HTTP_HOST} !^static\.mysite\.com
RewriteCond %{HTTP_HOST} !^static2\.mysite\.com
RewriteCond %{HTTP_HOST} !^staticcss\.mysite\.com
RewriteCond %{HTTP_HOST} !^staticjs\.mysite\.com
RewriteRule (.*) http://www.mysite.com/$1 [L,R=301]

plugin:
go to your admincp and create a new plugin in global_complete hook

Code:

$oz_process = str_replace('"http://www.mysite.com/clientscript/vbulletin_css/', '"http://staticcss.mysite.com/clientscript/vbulletin_css/', $output);
$oz_process = str_replace('"clientscript/vbulletin_css/', '"http://staticcss.mysite.com/clientscript/vbulletin_css/', $oz_process); 
$oz_process = str_replace('"http://www.mysite.com/clientscript/', '"http://staticjs.mysite.com/clientscript/', $oz_process); 
$oz_process = str_replace('"clientscript/', '"http://staticjs.mysite.com/clientscript/', $oz_process); 
$output = $oz_process;

So I was playing around with YSlow today and made some progress on improvements. Having some issues getting .js and some .css to compress with gzip but this is in Windoze.

I made a quick plug-in and hooked it as the last thing on global_start to swap out some of my images and other content to my subdomain CDN's. Not sure if my approach is correct but it seems to making YSlow happier anyway:

Code:

$oz_process = str_replace('"http://ozscience.com/forums/clientscript/', '"http://cdn8.ozscience.net/clientscript/', $output);
$oz_process = str_replace('"clientscript/', '"http://cdn8.ozscience.net/clientscript/', $oz_process);
// $oz_process = str_replace('"http://ozscience.com/common/', '"http://cdn8.ozscience.net/common/', $oz_process);
$oz_process = str_replace('"http://ozscience.com/forums/images/', '"http://cdn9.ozscience.net/images/', $oz_process);
$output = str_replace('"/forums/images/', '"http://cdn9.ozscience.net/images/', $oz_process);

images:
Go yo "templates and styles"
choose your style and then in Style Vars filter by imgdir
replace those PATHs with new-hostname/ + original path
IE: images/buttons -> http://static2.mysite.com/images/buttons

NOTE: because a bug in vb code here you can make a real mess, check this report first:

* Long story short:
a solution that worked for me was from David Grove:

The "fixes" described in the above comments are incorrect. To patch this issue, until v4.0.5 comes out, please edit line 489 of /admincp/stylevar.php, and change TYPE_ARRAY_ARRAY to TYPE_ARRAY.

So lines 485 through 491 should be changed from this:

PHP Code:

if ($_POST['do'] == 'savestylevar') { $vbulletin->input->clean_array_gpc('p', array( 'stylevar' => TYPE_ARRAY_ARRAY, 'original' => TYPE_ARRAY_ARRAY, ));

To this:

PHP Code:

if ($_POST['do'] == 'savestylevar') { $vbulletin->input->clean_array_gpc('p', array( 'stylevar' => TYPE_ARRAY, 'original' => TYPE_ARRAY_ARRAY, ));

This is of course, not the complete fix, but it will allow editing stylevars to work until v4.0.5 is released.

and you are done, now your site should be a bit faster
