Hello Ali, the request line you send is not valid HTTP/1.1.
Is there any particular reason why you want to implement HTTP yourself? There are open source packages that handle HTTP communication via proxy. Consider using HttpClient ;-) cheers, Roland "Ali Mohammed" <[EMAIL PROTECTED]> 21.12.2005 03:14 Please respond to "HttpClient User Discussion" To <[email protected]> cc Subject RE: Error with ProxyClient Hi, I'm able to make some progess and now I'm getting this other error. Here's the error message: Dec 20, 2005 6:08:08 PM org.apache.commons.httpclient.auth.AuthChallengeProcessor selectAuthScheme INFO: ntlm authentication scheme selected Connect failed: HTTP/1.0 404 Not Found Here's my code: public class ProxyTunnelDemo { ProxyClient proxyclient = new ProxyClient(); proxyclient.getHostConfiguration().setHost("http://www.yahoo.com";); proxyclient.getHostConfiguration().setProxy("genproxy.amdocs.com", 8080); proxyclient.getState().setProxyCredentials( new AuthScope("proxy_host", proxy_port, null, null), new NTCredentials("login_name", "password", "proxy_host", "domain")); // create the socket ProxyClient.ConnectResponse response = proxyclient.connect(); if (response.getSocket() != null) { Socket socket = response.getSocket(); try { // go ahead and do an HTTP GET using the socket Writer out = new OutputStreamWriter( socket.getOutputStream(), "ISO-8859-1"); out.write("GET http://www.yahoo.com/ HTTP/1.1\r\n"); out.write("Host: www.yahoo.com\r\n"); out.write("Agent: whatever\r\n"); out.write("\r\n"); out.flush(); BufferedReader in = new BufferedReader( new InputStreamReader(socket.getInputStream(), "ISO-8859-1")); String line = null; while ((line = in.readLine()) != null) { System.out.println(line); } } finally { // be sure to close the socket when we're done socket.close(); } } else { // the proxy connect was not successful, check connect method for reasons why System.out.println("Connect failed: " + response.getConnectMethod().getStatusLine()); //System.out.println(response.getConnectMethod().getResponseBodyAsString ()); } } Can anyone tell me what's going on here? I have been trying since 2 days now and I'm stumped. I found another piece of code on the net that dumps the content from the url and that works fine with proxy. Here's the code for that program: I don't understand why ProxyClient wouldn't work. package webconnector; import java.net.*; import java.io.*; import java.net.*; import java.util.Properties; public class CheckUrl { public static void main(String s[]) { new CheckUrl().dump("http://www.yahoo.com";); System.out.println("**************"); new CheckUrl().dump("http://www.paypal.com";); System.out.println("**************"); } public void dump(String URLName){ try { DataInputStream di = null; FileOutputStream fo = null; byte [] b = new byte[1]; // PROXY --------- jdk1.3.1 Properties systemSettings = System.getProperties(); systemSettings.put("proxySet", "true"); systemSettings.put("http.proxyHost","proxy_host") ; systemSettings.put("http.proxyPort", "proxy_port") ; URL u = new URL(URLName); HttpURLConnection con = (HttpURLConnection) u.openConnection(); sun.misc.BASE64Encoder encoder = new sun.misc.BASE64Encoder(); String encodedUserPwd = encoder.encode("domain\\login_name:password".getBytes()); con.setRequestProperty ("Proxy-Authorization", "Basic " + encodedUserPwd); // PROXY ---------- di = new DataInputStream(con.getInputStream()); while(-1 != di.read(b,0,1)) { System.out.print(new String(b)); } } catch (Exception e) { e.printStackTrace(); } } } Thanks.
