在Fat Free Framework中刷新响应头和主体

Question

In Fat Free Framework, is it possible to return HTTP headers and body (generated via template) to the browser before the end of a controller method? Looking for something akin to PHP's builtin flush() function. I want to return the response to the browser such that it doesn't expect any more data, and then run code that may take a long time.

Possible duplicate of fat-free framework flush partial output, so see there for some solutions. Also worth trying is the $f3->abort() feature, see https://fatfreeframework.com/3.6/base#abort
