     * producing invalid output code -- and (b) strips licenses, which would certainly get us
     * into legal trouble.
     * 
     * We also disable GZIP compression here, and instead rely on a centralized GZIP filter.
     * This is because only JavascriptPackageResource uses Wicket's built-in compression;
     * CSS resources for example do not. Wicket also doesn't set the Vary: HTTP header.
     * Centralized GZIP handling (and caching) should be more manageable.
