    <p>There's a thrird party app that needs to get information via custom http headers, so I wrote a simple test app that creates this headers and then redirects to a page that lists all headers.</p> <p>The header-generating servlet snippet is:</p> <pre><code>protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/plain"); response.setHeader("cust-header", "cust-val"); response.sendRedirect("header.jsp"); } </code></pre> <p>On the other hand, the relevant code from header.jsp is:</p> <pre><code>&lt;% Enumeration enumeration = request.getHeaderNames(); while (enumeration.hasMoreElements()) { String string = (String)enumeration.nextElement(); out.println("&lt;font size = 6&gt;" +string +": " + request.getHeader(string)+ "&lt;/font&gt;&lt;br&gt;"); } %&gt; </code></pre> <p>That displays the following headers:</p> <pre><code>Host: localhost:9082 User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; es-ES; rv:1.9.2.10) Gecko/20100914 Firefox/3.6.10 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: es-es,es;q=0.8,en-us;q=0.5,en;q=0.3 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Referer: http://localhost:9082/HdrTest/login.jsp Cookie: JSESSIONID=0000tubMmZOXDyuM4X9RmaYYTg4:-1 </code></pre> <p>As if the custom header was never inserted. How can I fix it ?</p> <p>Thanks</p>

Guidance
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.
