You can turn off circular redirect checking. You haven't said what version of the library you're using. Assuming the latest, take a look at RequestConfig.Builder. There are other options/mechanisms for raising the limits, or taking part in the analysis process.

We were able to hit the same server with a simple standalone java program, Mozilla and Chrome ReST client which is working fine where as the Apache client libraries is throwing the above mentioned exception. I have pasted the code snippet below and java program, please help me overcome this situation. The Authorization header is intentionally garbled for security reasons however with the code error is reproduced and with proper header also we see the problem. DefaultHttpClient httpclient = new DefaultHttpClient(); try { KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType()); FileInputStream instream = new FileInputStream(new File("C:\\IBMJDK7\\jre\\lib\\security\\cacerts")); try { trustStore.load(instream, "changeit".toCharArray()); } finally { try { instream.close(); } catch (Exception ignore) {} } SSLSocketFactory socketFactory = new SSLSocketFactory(trustStore); Scheme sch = new Scheme("https", 443, socketFactory); httpclient.getConnectionManager().getSchemeRegistry().register(sch); HttpGet httpget = new HttpGet(" https://login.eloqua.com:443/id/ "); httpget.addHeader("Authorization", "Basic VGVjaG5vbG9neVBhcnRuZXJQZXJzaX"); httpget.addHeader("Accept","application/json"); System.out.println("executing request" + httpget.getRequestLine()); HttpResponse response = httpclient.execute(httpget); HttpEntity entity = response.getEntity(); System.out.println(response.getStatusLine()); if (entity != null) { System.out.println("Response content length: " + entity.getContentLength()); } EntityUtils.consume(entity); } finally { httpclient.getConnectionManager().shutdown(); } Sample Java Code public class TestEloquaJavaHttpUrl { public static void main(String [] args) throws Exception { // configure the SSLContext with a TrustManager SSLContext ctx = SSLContext.getInstance("SSLv3"); ctx.init(new KeyManager[0], new TrustManager[] {new DefaultTrustManager()}, new SecureRandom()); SSLContext.setDefault(ctx); URL url = new URL("https://login.eloqua.com:443/id/";); HttpsURLConnection conn = (HttpsURLConnection) url.openConnection(); conn.setRequestProperty("Authorization", "Basic VGVjaG5vbG9neVBhcnRuZXJQZXJzaX"); conn.setRequestProperty("Accept", "application/json"); conn.setHostnameVerifier(new HostnameVerifier() { @Override public boolean verify(String arg0, SSLSession arg1) { return true; } }); System.out.println(conn.getResponseCode()); conn.disconnect(); } private static class DefaultTrustManager implements X509TrustManager { @Override public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {} @Override public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {} @Override public X509Certificate[] getAcceptedIssuers() { return null; } } } -- Regards, Srihari NA
