> Project: HttpComponents HttpCore

>
> One of the nice things about chunked encoding is that you can send your data
> in little parts.
> However, flush() on ChunkedOutputStream does not flush the buffer:
>
> /**
> * Flushes the underlying stream, but leaves the internal buffer alone.
> * @throws IOException
> */
> public void flush() throws IOException {
> this.out.flush();
> }
> This is kind of against the spec of flush on OutputStream:
>
> /**
> * Flushes this output stream and forces any buffered output bytes
> * to be written out. The general contract of <code>flush</code> is
> * that calling it is an indication that, if any bytes previously
> * written have been buffered by the implementation of the output
> * stream, such bytes should immediately be written to their
> * intended destination.
> * ...
> Generally if a client does not want to flush the data they won't call flush,
> which will cause all the chunks to attain the full chunk size anyway...
> The fix would be to add a flushCache() call right before this.out.flush().
> Currently I'm using my own subclass of ChunkedOutputStream which does exactly
> this and it works perfectly; the chunks in my application have the full size
> 99% of the time (unless I explicitly flush in the writeTo(OutputStream)
> method of my Entity).
