copied!<p>Try sending them in chunks along with <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.41" rel="noreferrer"><code>Transfer-Encoding:</code></a> <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.6.1" rel="noreferrer"><code>chunked</code></a>. More details in <a href="http://en.wikipedia.org/wiki/Chunked_transfer_encoding" rel="noreferrer">wikipedia</a>.</p> <p><strong>Update</strong> as per the comments, here's an example how a "ChunkedOutputStream" in Java may look like:</p> <pre><code>package com.stackoverflow.q2395192; import java.io.IOException; import java.io.OutputStream; public class ChunkedOutputStream extends OutputStream { private static final byte[] CRLF = "\r\n".getBytes(); private OutputStream output = null; public ChunkedOutputStream(OutputStream output) { this.output = output; } @Override public void write(int i) throws IOException { write(new byte[] { (byte) i }, 0, 1); } @Override public void write(byte[] b, int offset, int length) throws IOException { writeHeader(length); output.write(CRLF, 0, CRLF.length); output.write(b, offset, length); output.write(CRLF, 0, CRLF.length); } @Override public void flush() throws IOException { output.flush(); } @Override public void close() throws IOException { writeHeader(0); output.write(CRLF, 0, CRLF.length); output.write(CRLF, 0, CRLF.length); output.close(); } private void writeHeader(int length) throws IOException { byte[] header = Integer.toHexString(length).getBytes(); output.write(header, 0, header.length); } } </code></pre> <p>...which can basically be used as:</p> <pre><code>OutputStream output = new ChunkedOutputStream(response.getOutputStream()); output.write(....); </code></pre> <p>You see in the source, every chunk of data exist of a header which represents the length of data in hex, a CRLF, the actual data and a CRLF. The end of the stream is represented by a header denoting a 0 length and two CRLFs.</p> <p><strong>Note:</strong> despite the example, you actually do <strong>not</strong> need it in a JSP/Servlet based webapplication. Whenever the content length is not set on a response, the webcontainer will automatically transfer them in chunks.</p>
