    <p>I want to access my web site that first requires a basic authorization, and then post the parameters (search keyword) to my home page.</p> <p>My code can pass the basic authorization and will get the response text, however I cannot get the search result but get the home page code instead.</p> <p>As such, I printed the parameters.size() and it return 0, so I doubt the HttpClient redirect method does not pass the parameters after basic authorization.</p> <p>Following my code, which is trying to get the search result:</p> <pre><code>List&lt;NameValuePair&gt; params = new ArrayList&lt;NameValuePair&gt;(); params.add(new BasicNameValuePair("search_keyword", "test")); params.add(new BasicNameValuePair("search_size", "50")); DefaultHttpClient httpclient = new DefaultHttpClient(); httpclient.setRedirectStrategy(new DefaultRedirectStrategy() { public boolean isRedirected(HttpRequest request, HttpResponse response, HttpContext context) throws ProtocolException { boolean isRedirect=false; try { isRedirect = super.isRedirected(request, response, context); } catch (ProtocolException e) { throw e; } if (!isRedirect) { int responseCode = response.getStatusLine().getStatusCode(); if (responseCode == 301 || responseCode == 302) { return true; } } return isRedirect; } }); String encoding = Base64Encoder.encode("admin:password"); HttpPost httppost = new HttpPost("http://127.0.0.1/MySystem/home"); httppost.setHeader("Authorization", "Basic " + encoding); httppost.setEntity(new UrlEncodedFormEntity(params, "UTF-8")); //Execute and get the response. HttpResponse response = httpclient.execute(httppost); int responseCode = response.getStatusLine().getStatusCode(); switch(responseCode) { case HttpURLConnection.HTTP_OK: HttpEntity entity = response.getEntity(); List&lt;NameValuePair&gt; parameters = new ArrayList&lt;NameValuePair&gt;(URLEncodedUtils.parse(entity)); System.out.println("parameters size: "+parameters.size()); for(NameValuePair p:parameters) System.out.println("parameter: "+ p.getName() + p.getValue()); if(entity != null) { responseText = EntityUtils.toString(entity); System.out.println("responseText: "); System.out.println(responseText); } break; default: throw new Exception("Failed to pass the basic authorization. Response code: "+responseCode); } </code></pre> <p>Updated:</p> <p>The following condition will return true:</p> <pre><code>if (responseCode == 301 || responseCode == 302) { return true; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
