[undertow-dev] Undertow 1.3.0 - rewrite HTML content

[Miere Teixeira]

I'd suggest you to create a random token (or any minor release number) and
store it at the build time. Then, use it as a query parameter on your
asset... Something like this:

<link rel="stylesheet" href="/css/theme.css
<http://localhost:9090/css/theme.css>?yourTokenWillBeHere" />

Last, but not the least, use a template engine like JMustache
<https://github.com/samskivert/jmustache> or Freemarker to this. They used
to be versatile enough to handle HTML rendering and offers a nice API to
define template variables.

I'm sure there must be an easier approach, like Grails used to do, but I
think this would be good enough.
