Thanks for the heads up. Unfortunately, after I set that option, I found that it this is not the problem. Still, now I have one item eliminated.
I don't think there is anything I am doing incorrectly because my client side app never reports a problem when not going through the proxy. However, I can't prove it. And it could be that maybe I am not doing something incorrectly that my client java app is more tolerant of than the proxy. Does anyone have anymore ideas on why this is happening? I am just writing to the OutputStream I get from the response and then I close the stream. Is there more I need to do when I am done sending a response?
