ServletOutputStream out = response.getOutputStream();
// Writing large data amounts (problems for >200MB) to out
// Tried different variants of flush() and flushBuffer() during this writing
The code being used for handling "out" seems to be a org.ajax4jsf.webapp.FilterServletResponseWrapper$ByteArrayServletOutputStream which in turn relies on org.ajax4jsf.io.FastBufferOutputStream to do the actual work.
I have checked this FastBufferOutputStream (and FilterServletResponseWrapper) and they do write all data to in-memory byte arrays.
Question: Is it possible at all to send data to the client before close() and responseComplete() is called? If so can the above classes be configured to do so?
