If set, then a long cache header is sent. If this is omitted then a no-cache header is sent. You can use this if you f.e. know the last modified date of a sample. Stick the last modified date in the cache key, so the sample can be stored in browser cache (and will automatically be invalidated if the modified date changes).
Impulse ID. If this is unset then the default impulse is used.
