[vinay basavanal]

HI All,

I am getting http server reponse code 400 when i am running below but however it runs fine when i have proxy configured in my server

URL url = new URL(reqUrl);
	HttpURLConnection con = (HttpURLConnection)url.openConnection();
	con.setDoOutput(true);
	con.setRequestMethod(request.getMethod());
	if(request.getContentType() != null) {
	  con.setRequestProperty("Content-Type", request.getContentType());
	}
  con.setRequestProperty("Referer", request.getHeader("Referer"));
	int clength = request.getContentLength();
	if(clength > 0) {
		con.setDoInput(true);
		InputStream istream = request.getInputStream();
		OutputStream os = con.getOutputStream();
		final int length = 5000;
	  byte[] bytes = new byte[length];
	  int bytesRead = 0;
	  while ((bytesRead = istream.read(bytes, 0, length)) > 0) {
	    os.write(bytes, 0, bytesRead);
	  }
	}
  else {
    con.setRequestMethod("GET");
  }
	out.clear(); 
  out = pageContext.pushBody();
	OutputStream ostream = response.getOutputStream();
	System.out.println(" finished getOUTputsteram");
	response.setContentType(con.getContentType());
	
	InputStream in = con.getInputStream();
	
	final int length = 5000;
  byte[] bytes = new byte[length];
  int bytesRead = 0;
  while ((bytesRead = in.read(bytes, 0, length)) > 0) {
    ostream.write(bytes, 0, bytesRead);
  }
