    <p>I'm trying to add a referer to an http post in Apache HttpClient (httpclient-4.0-beta2).</p> <p>I found some sample code that does this. The code works, but I'm wondering if there is not a simpler, more straightforward way to add the referer than using the (ominously named) addRequestInterceptor, which appears to take an (yikes!) inner class as a parameter.</p> <p>The code in question begins below with "// add the referer header". I'm a novice, and this code is doing several things that I don't understand. Is this really the simplest way to add a referer to my http post?</p> <p>Thanks for any pointers.</p> <pre><code>// initialize request parameters List&lt;NameValuePair&gt; formparams = new ArrayList&lt;NameValuePair&gt;(); formparams.add(new BasicNameValuePair("firstName", "John")); formparams.add(new BasicNameValuePair("lastName", "Doe")); // set up httppost UrlEncodedFormEntity entity = new UrlEncodedFormEntity(formparams, "UTF-8"); HttpPost httppost = new HttpPost(submitUrl); httppost.setEntity(entity); // create httpclient DefaultHttpClient httpclient = new DefaultHttpClient(); // add the referer header, is an inner class used here? httpclient.addRequestInterceptor(new HttpRequestInterceptor() { public void process(final HttpRequest request, final HttpContext context) throws HttpException, IOException { request.addHeader("Referer", referer); } }); // execute the request HttpResponse response = httpclient.execute(httppost); </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.
