Forcing Apache To Attach Code To Web Pages

[fixago]

How would one go about making Apache attach a snippet of code to every web page? For example, let's say I own a hosting company, and I offer free hosting. Someone signs up for the free hosting, but Apache attaches a piece of code to every page they create. It's the same thing, for example, GoDaddy does with their free hosting. Here's an example:

<snip>

That header is called via JavaScript, which is parsing an IFRAME to display the ads, Google search, and link backs to GoDaddy.

How would one achieve the same thing?

There is no native support for this in Apache. You can use PHP server-side or JavaScript on the client-side to do this. If you use a server-side solution, be sure to exclude non-page filetypes from having code prepended: image files, CSS files, external JS files, robots.txt, /w3c/p3p.xml, labels.rdf, etc.
