turnin on the gzip compression. Very useful when using a controller for your application (you only need to include once)
<?php
if (substr_count($_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip')) ob_start("ob_gzhandler"); else ob_start();
?>

Better loading of styles on a Rails Application :-)
%h1 When using HAML, or even the rails .erb format, you can improve the loading of your pages using:
= stylesheet_link_tag controller.action_name
%span Or
= stylesheet_link_tag self.current_method
%span And create the proper CSS file in the public/style folder (e.g.: action_name.(s)css/ current_method.(s)css.
With this, the user only requests the CSS file from that page he is visiting.
