Help me...How to read the content if "Transfer-Encoding:chunked" is used?

Question

I am doing a project for internet control using Java,PHP and MySql.All sites should go through the proxy server only.If the HTTP header contains Content-Length,am getting the content length as below:
public class HTTPResponseReader extends HTTPMessageReader
    String statusCode;
    public HTTPResponseReader(InputStream istream) throws IOException,                     NoSuchElementException
  BufferedInputStream distream = new BufferedInputStream(istream);
  retrieveHeader(distream);
  StringTokenizer st =  new StringTokenizer(new String(HTTPMessageReader.toArray(header)));
  versionProtocol = st.nextToken();
  statusCode = st.nextToken();
  String s;
  while (st.hasMoreTokens())
        s = st.nextToken();
        if (s.equals("Transfer-Encoding:"))
       transferEncoding = new String(st.nextToken());
     if (s.equals("Content-Length:"))
       contentLength = Integer.parseInt(st.nextToken());
     if (s.equals("Connection:"))
      connection = new String(st.nextToken());
      if (connection.equals("keep-alive")) mustCloseConnection = false;
   retrieveBody(distream);     
}After getting the Content-Length,i used read method to read the content upto that content length.Then i concatenated the HTTP header and body and the requested site was opened.But some sites dont have Content-Length.Instead of that,Transfer-Encoding is used.I got the HTTP Response header as "Transfer-Encoding:chunked" for some sites.If this encoding is used how to get the length of the message body and how to read the content.
Can anybody help me.
Thanks in advance...

Why don't you use HttpUrlConnection class to retrieve data from HTTP server? This class already supports chunked encoding...
If you want to do anything by yourself then you need to read HTTP RFC and find all required information. Well in two words you may reject advanced encoding by specifying HTTP 1.0 in your request or download chunked answer manually. Read RFC anyway :)
