    <p>I have the following jquery code</p> <pre><code> $('#spam').click(function () { $.ajax({ type: 'GET', url: 'http://www.my-contacts.com/contacts/api/contacts', dataType: 'json', contentType: 'application/json; charset=utf-8', headers: { 'Authorization=': 'Bearer ' }, }).done(function () { alert("success"); }) .fail(function (xhr, textStatus, errorThrown) { console.log(xhr); alert("Error:" + xhr); }); }); </code></pre> <p>The browser send the preflight request with options and get a 200 from the server (I have arranged with a handler that is called). Below are the headers</p> <pre><code>**Response Headers view source** Access-Control-Allow-Head... Authorization, X-Authorization Access-Control-Allow-Meth... GET, POST, PUT, DELETE, HEAD, OPTIONS Access-Control-Allow-Orig... * Cache-Control no-cache Content-Length 0 Date Fri, 13 Dec 2013 12:01:18 GMT Expires -1 Pragma no-cache Server Microsoft-IIS/7.5 X-AspNet-Version 4.0.30319 X-Powered-By ASP.NET **Request Headers view source** Accept text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Encoding gzip, deflate Accept-Language en-US,en;q=0.5 Access-Control-Request-He... content-type Access-Control-Request-Me...

However it finally came down to JQuery not working well with CORS (at least the version that I am using 1.8.2 but I tried 1.10 too)</p> <p>I changed the code with </p> <pre><code>(function () { x = new XMLHttpRequest(); x.open('GET', 'http://www.my-contacts.com/contacts/api/contacts', false); x.onreadystatechange = function () { if (x.readyState === 4) { console.info(x.responseText); } }; x.setRequestHeader("Content-Type", "text/plain;charset=UTF-8"); x.setRequestHeader('Authorization', 'Bearer ' + accessToken); x.send(''); })(); </code></pre> <p>But this code does not work with IE or FF. Chrome on the other hand works perfectly. The other two give me an error with <code>x.send('')</code></p>

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.

SQuiL has stopped working due to an internal error.

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