I am writing a small proxy server which listens on a port that I set my browser to use as a proxy. So far, it works in as much as it sucessfully gets requests from the browser through a socket, spawns a thread to handle the request which retrieves the web resource, and passes it back to the browser which displays the HTML or other text.

The problem I am having is with retrieving images. All images show as broken in the rendered HTML. I am assuming the cause is that I am not properly handling binary files. The code (condensed version) I have for handling HTML ( which works ) is :

			

			ServerSocket s   = new ServerSocket(4321);
			

			Socket  incoming = s.accept();
			

			PrintWriter out  = new PrintWriter( incoming.getOutputStream(), true /*autoflush*/);
			

			URL u = new URL("http://some.host.com/index.html");
			

			URLConnection connection = u.openConnection();
			

			connection.connect();
			

			BufferedReader inPage = new BufferedReader( new InputStreamReader( connection.getInputStream()));
			

			String line;
			

			while ( (line=inPage.readLine()) != null )
			

			{
			

			out.println(line);
			

			}
			

		

This ( I guess obviously ) doesn't work for images, again I assume because the code is for a character stream when it should be a byte stream. I tried InputStreamReader and DataInputStream but without success; perhaps because I am using them incorrectly.

Can anyone guide me in the right direction, and tell me how to mod the code above to work when the URL in question points to a binary file ( images, pdf's, etc )?

Any help would be greatly appeciated.

Thnx,
