Right. After a certain number of characters have been sent to the output stream (8192 by default, I think), the buffer is flushed and the first byte (along with others) is sent to the client. This usually includes all the HTTP response headers, and certainly will include the response header (the first header sent back to the client). After the response header has been sent, you cannot change it. > so, if I want to get the exception during the data transferring in the > client, do you guys have any idea hot to do that? Once you've sent a certain amount of data, you will not be able to change the response code. That's why it's a good idea to do all the work that could fail /before/ you start sending data back to the client. Of course, this is not always practical, but a reasonable goal.
