Return Plugin

return stops executing the current sequence and signals the runtime to return control to the caller (if any). It is a control-flow primitive used to short-circuit sequence execution without modifying the response.

Exec quick-setup

• Quick: return — used as exec: return to stop the current sequence.

Args

• This plugin takes no arguments; the quick-setup string must be exactly return with no trailing data.

Behavior

• When executed, return sets the internal RETURN_FLAG and halts further execution of the current sequence.
• If the current sequence was invoked via jump, control returns to the caller sequence; otherwise execution simply stops for the active sequence.
• It does not create or modify DNS responses or other metadata beyond the return flag.

When to use

• Exit a sequence early after performing local checks or side-effects (e.g., logging or metrics) so the caller can resume.
• Use inside helper sequences invoked with jump when you want to return control to the originator without accepting/rejecting the response.

Examples

• Stop a helper sequence and return to caller:

- exec: some_helper_sequence
- exec: return

• Use return when you want the caller sequence to continue after a jump-based helper finishes.
