Hello,After some more search and reading, here is the sample code that I am trying out: HttpClient httpclient = new DefaultHttpClient(); HttpContext localContext = new BasicHttpContext(); HttpGet httpget = new HttpGet("targetURL"); AuthScope proxyScope = new AuthScope(proxyHost, proxyPort); AuthScope targetScope = new AuthScope(targetHost, targetPort); AuthState proxyAuthState = new AuthState(); proxyAuthState.setAuthScope(proxyScope); proxyAuthState.setCredentials(new UsernamePasswordCredentials(proxyUser, proxyPassword) ); localContext.setAttribute(ClientContext.PROXY_AUTH_STATE, proxyAuthState); AuthState targetAuthState = new AuthState(); targetAuthState.setAuthScope(targetScope); targetAuthState.setCredentials(new UsernamePasswordCredentials(webSiteUser, webSitePassword) ); localContext.setAttribute(ClientContext.TARGET_AUTH_STATE, targetAuthState); HttpHost proxy = new HttpHost(proxyHost, proxyPort); httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy); HttpResponse response = null; HttpHost targetHost = new HttpHost(targetHost, targetPort, "https"); try { response = httpclient.execute(targetHost, httpget); System.out.println("----------------------------------------"); System.out.println(response.getStatusLine()); } catch(Exception e) { System.out.println("Exception " + e.toString()); } And I get the following output: Oct 26, 2009 12:02:01 PM org.apache.http.impl.client.AbstractAuthenticationHandler selectScheme WARNING: Authentication scheme ntlm not supported Oct 26, 2009 12:02:01 PM org.apache.http.impl.client.DefaultRequestDirector createTunnelToTarget WARNING: Authentication error: Unable to respond to any of these challenges: {kerberos=Proxy-Authenticate: Kerberos, ntlm=Proxy-Authenticate: NTLM, negotiate=Proxy-Authenticate: Negotiate} ---------------------------------------- HTTP/1.1 407 Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request.

Hello, We are trying to use HttpClient 4.0 API to connect to an internet website that requires user authentication to retrieve files. And we connect to the internet through a proxy that also needs a different user credentials. All the samples that I have seen so far, do either proxy authentication or web-site authentication but not both: a) Is the scenario I explained above, achievable using HttpClient? I guess it should be possible, but I am not sure how? Can someone help me with this And for info, the production environment will be on Linux and the development environment is Windows..
