Bandwidth saver

I never miss an opportunity to push for Freemarker, the most powerful template engine in the world, so here's a quick tip on how to strip all whitespace from your HTML pages:

<#assign out>
!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "">

// Your page here


It assigns the compressed body of the outer assign macro to the variable "out", and the finally writes the value of "out" with all newlines stripped.

The entire page is now a singe line of HTML - a developer's nightmare, but a nice a bandwidth saver.

Combined with Sitemesh, another one of my favorite tools, this is easily and transparently applied to all your pages.
