Pair framework: EmptyResponse

Pair\Http\EmptyResponse is an explicit response object for status-only responses.

It sends configured headers and an HTTP status code without emitting a body.

Constructor

new EmptyResponse(int $httpCode = 204, array $headers = [])

Arguments:

• httpCode: HTTP status code.
• headers: additional response headers keyed by header name.

Example:

use Pair\Http\EmptyResponse;

return new EmptyResponse(304, [
	'ETag' => '"abc123"',
	'Cache-Control' => 'public, max-age=300',
]);

Typical use

EmptyResponse is mainly used by HttpCache for 304 Not Modified responses.

Use JsonResponse or TextResponse when the endpoint has a response body.

When APP_DEBUG=true and observability debug headers are enabled, send() also emits Pair correlation and trace timing headers.
