I am working on a reverse proxy using undertow, and I have just added debugging support, where I can add a request/response wrapper to the exchange and save/trace/debug the result.

I noticed that for persistent connections, those wrappers seem to be kept on the exchange when subsequent requests arrive - even after endExchange() has been called on the first request.

Can that be true ? Is there something I need to do to cleanup when the exchange ends ? or should they have been removed in closeAndFlushResponse() ?
