Excellent article.

“add expires headers to the response. I originally thought about doing it with PHP”

How can you do this in PHP ? Can you write a script? I tried to add expires headers to my .htacess but y-slow shows no change
any ideas?

Thanks

Please note, if you wish to use “Header set Cache-Control “must-revalidate” ” for the expire tags, then in your apache config you will most likely need to have mod_headers enabled. I didn’t realize mine was disabled and apache was mad on restart.

@Pascal, thanks for the tip. I updated the post. A whitelist is a great idea but I included a rudimentary check in the post with a comment to include the appropriate checks.

This is rather dangerous.
What if somebody enters a URL such as http://www.jaisenmathai.com/js/compress-aaa.js|prototype.lite.js|javascript.js|serverscript.php

replace serverscript.php with any php-file that runs on your server. People will be able to read the contents and discover further security issues, maybe your database configuration and more. Don’t use that method without checking the content of __args__ against a white list.

@Leonie, Very cool. I’ll definitely give that a try. Thanks for sharing.

hey jaisen,
I have pretty good experiences with minify [http://code.google.com/p/minify/].

It groups js and css files, minifies them, handles the gzip and the corresponding headers. You can also define dynamic groups and don’t have to worry about users using outdated scripts. The dynamic group checks for the last modification date of every single file in your groups and creates a timestamp-path.

It is very easy to install / use too.

@Alfred. Unfortunately the JS files that YSlow complains about are 3rd party JavaScript files. One being for Google Analytics and the other being for the Photagious API.

You still need to minify your javascript files for better gzip compression(Because minified javascript compresses even better). Test it out with stats from Yslow and you get a B for #10 and not an A. For the rest nice article.
