Re: [gatein-dev] SessionManagerContainer in exo.kernel.container 2.5.0-Alpha3

Hi Nick thank you for your help, see below my comments: Writing the response into memory would of course work but it is clearly not an option for obvious reasons. I'm not sure I understand what you mean by "For WS-284 could you still write the response out but then supply an error code later ?" If the "response" is already written I don't see how it would be possible to change the status code (I guess it is what you mean by error code) later knowing that the status code is part of the header which is written before the body that contains the "response". Even if it was possible we would have an inconsistency between the body and the status code which will be seen as a bug for many customers/partners/consultants So I keep on saying that there is nothing I can do on my side, unless you have other suggestions. If not as it is not possible to improve the code on gatein, I will revert the changes for WS-284 within the context of 285

For WS-284 could you still write the response out but then supply an error code later ? So at least you have an error from the server even though the response has been written out. When I looked at this awhile ago - I was playing with writing the response into memory, but that obviously won't scale.
