Hi, 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() ? -- Med venlig hilsen / Best regards *Kim Rasmussen* Partner, IT Architect *Asseco Denmark A/S* Kronprinsessegade 54 DK-1306 Copenhagen K Mobile: +45 26 16 40 23 Ph.: +45 33 36 46 60 Fax: +45 33 36 46 61
