net.i2p.router.web.ContentOnly
public class ContentOnlyextends Object
Per-request utility for the opt-in console fragment mode. When a page is requested with a contentonly request parameter, only the named elements are rendered and the shared head/sidebar chrome is skipped, so auto-refresh ticks transfer and parse a fraction of the full page. Full-page requests (no contentonly parameter) are unaffected.

Pages opt in by gating each refresh target with render(HttpServletRequest, String); the chrome guards in head.jsi and sidebar.jsi are shared by every console page.
