Displays nested content or "then" child once, then sets a cookie with $ttl, optionally locked to domain name, which makes the condition return FALSE as long as the cookie exists.
"Once"-style ViewHelpers are purposed to only display their nested content once per XYZ, where the XYZ depends on the specific type of ViewHelper (session, cookie etc).
