Normally (with all web frameworks, not just Dancer) the request handler
returns a status when it's finished.  The status code, headers, and
content make up the response, which is the output of the request
handler back to the user agent (which initiated the request).  If
something else were to be done with the content afterwards, it would be
done either in the user agent or in a subsequent request sent by the
user agent.

Maybe you should explain more about what you're doing and why.  I don't
know anything about Stripe, but maybe you need to add another type of
hook in Stripe that does something with the response content after it
comes back from the webhook.
