manually close the connection after ctx.body
I have a route like this:
api.put('/my/path', mdw0, body({fields:'body'}),mdw1, mdw2, controller);

The first middleware mdw0 reads some headers before the body is parsed and might decide to send an error if the size is > allowed_size or to call await next()

The problem is that the connection remains active till the end of the upload, so I don't have any advantage in using this strategy, the actual response with 413 arrives to the browser immediately if I kill the node process otherwise it remains in pending till the end.

So, how can i manually end the connection after i set ctx.status and ctx.body?
