gzip your CSS

Step 1
Create a new file, call it 'gzip-css.php' copy the following snippet and upload to the 'vbulletin_css' folder:

PHP Code:


		
			
<?php

ob_start('ob_gzhandler');

header('Content-type: text/css; charset: UTF-8');

header('Cache-Control: must-revalidate');

header('Expires: Thu, 3 Jan 2007 23:53:18 GMT');

?>

Step 2
create a .htaccess file, put this in the same directory as above, put in the following snippet:

PHP Code:


		
			
php_value auto_prepend_file gzip-css.php

Step 3
Open the adminfunctions_template.php file located in the 'includes' directory. Look for the following:

PHP Code:


		
			
$cssfilename = 'clientscript/vbulletin_css/style-' . substr(md5(microtime()), 8, 8) . '-' . str_pad($styleid, 5, '0', STR_PAD_LEFT) . '.php';

change it to

PHP Code:


		
			
$cssfilename = 'clientscript/vbulletin_css/style-' . substr(md5(microtime()), 8, 8) . '-' . str_pad($styleid, 5, '0', STR_PAD_LEFT) . '.css';

Now login to you vb control panel, re-generate the css file and your done. Enjoy ;)

umm gzip css ?
confused... it should help to load the page faster ?

mod_gzip ..its possible to use it in shared server?

Hmm, I wouldn;'st suggest that, at least if I understand some things. I believe that IE has some issues cacheing gziped pages, and the CSS file should only be requested a few times before cached, thus why we have it as a file.

No... this means your server zipping up your .ccs file before sending to your browser. Thus less bandwidth usage... although I don't see the real point of this hack as .css files downloaded only once or twice than stored for weeks/months (if no changes in .css sizes) by all modern browsers.

Zia	03-19-2006 06:48 AM

hmm then no need to use this att all....

Good work..

But is there any increase in performance?

Zachery

Increase preformace would be removing gzip, decreasing preformance would be adding it back.

This is pointless since browsers cache all css and javascript when they are seperate files. It IS why you should always have them in a seperate file. Most webservers are running mod_deflate or equivilents that compress text in a way that browser can interpret. Browsers check and compare the time and date of last update for css and javascript files before downloading. So unless you have changed the css file, they will not be downloading the css in the first place.

But, do as you please.

Personally, I think gzipping css files will not add as much bandwidth savings as gzipping .php files would but more bandwidth savings and faster initial page loads make doing something like this worth it.
