AsyncMiddleManServlet
is a proxy servlet dedicated to mutate content.
If you don't need to mutate content, don't use it, and use instead ProxyHandler
(recommended) or AsyncProxyServlet
.
As for AsyncMiddleManServlet
, did you actually follow the advice I gave in the comment?
Does it not work?
If it does not work, we need details, because it is supposed to work like you expect.

Continuing the discussion from https://github.com/jetty/jetty.project/issues/12294#issuecomment-2374287136 as this is a separate topic.
The proxy servlets(in particular
AsyncMiddleManServlet
, as that is what I am looking at) do not seem to flush responses as the proxy client receives new bytes. Ideally it should auto flush in an optimal way(for ex. if http1.1 and chunked, it should flush on each full chunk). Otherwise there could be huge delays between when the data is available and when it is actually returned to the caller(due to buffering). Since this is a proxy, I expected this to be the default, otherwise I hope to be able to set it up that way.The
ContentTransformer
does not seem to provide a way to control this(suggested in the previous github question). That abstraction is about mutating the raw data in some way.The only way that I can see from the code of
AsyncMiddleManServlet
is to callflush
on theServletOutputStream
right afterProxyWriter
callswriteProxyResponseContent
. Unfortunatly that method is package private so the only way is to override the entireonWritePossible
and flush afterward.What would you advise is the right way to do this?
