    <p>When I execute a simple <em>XML HTTP Request</em> from my server using the code below</p> <pre><code>var targetUrl = "http://server/Service1.svc?input1=uno&amp;input2=duo"; document.getElementById("console").innerHTML += "&lt;br&gt;commencing"; var xhr = new XMLHttpRequest(); xhr.onload = function () { document.getElementById("console").innerHTML += "&lt;br&gt;callbacking"; alert(xhr.responseText); } xhr.open("GET", targetUrl); document.getElementById("console").innerHTML += "&lt;br&gt;finishing"; xhr.send(); </code></pre> <p>I get status code 302 in the console of FireBug. According to <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html" rel="nofollow noreferrer">this W3 article</a>, status code 302 means that the resource is temporarily redirected. I'm not fully certain on what that mean in my case because when I type my URL into the FireFox, I get the response as supposed to, looking great.</p> <p>There are numerous articles regarding this issue but I can't get it straight. For instance, <a href="https://stackoverflow.com/questions/12420686/how-to-correctly-deal-with-302-status-code">this one</a> only restates the definition of the status code. <a href="https://stackoverflow.com/questions/6299021/ajax-and-status-302">This one</a> suggests to use <em>HEAD</em> instead of <em>GET</em> but that's not an option in my case (unless absolutely necessary). <a href="https://stackoverflow.com/questions/7524039/problems-with-xmlhttprequest-status-302">Here</a> it's even claimed that the status code 302 <strong>automatically</strong> leads to a correct redirect to the plac ewhere the page moved to (resulting in status code 200), which in my case isn't true.</p> <p>I've tried looking at <code>xhr.getRespoonseHeader("Content-Type")</code> but, apparently, it's <code>null</code>.</p> <p>I'm stuck. What can I do about my problem?</p>

    2. COHave you looked at a tool like Fiddler and see what happens? I am guessing your server is correcting a url, but without seeing code, live demo, it is hard to say.

    3. CO@MrCode Not sure. I haven't set that explicitly and I don't know how to check if it's enabled (installed?) by default. Are we talking server side (which I'll have a slight problem changing) or client side (where I have full freedom of action)?

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
