    <p>I have encountered a really strange behavior of the URLLoader/URLRequest. Take a look at the following code: </p> <pre><code>var loader:URLLoader = new URLLoader(); loader.dataFormat = URLLoaderDataFormat.BINARY; var request:URLRequest = new URLRequest(url); request.method = URLRequestMethod.POST; if (params.action is ByteArray) { params.action = Base64.encodeByteArray(params.action); } var vars:URLVariables = new URLVariables(); for (var paramName:String in params) { vars[paramName] = params[paramName]; } request.data = vars; loader.load(request); </code></pre> <p>And when I check HTTP raw request I see this: </p> <pre><code>POST /actions/send/3882-fba04fd1db5b0ac4f4107dd06632e851 HTTP/1.1 Host: domainname.com Content-Length: 237 Origin: http://anotherdomain.com User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_4) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.168 Safari/535.19 Content-Type: application/x-www-form-urlencoded Accept: */* Referer: http://anotherdomain.com/page.html Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 Cookie: foo=bar Pragma: no-cache Cache-Control: no-cache Content-type: application/x-www-form-urlencoded Content-length: 165 action=BASE64DATABASE64DATABASE64DATABASE64DATABASE64DATABASE64DATABASE64DATA </code></pre> <p>So.. wtf? Why URLLoader inserts <code>\r\n</code> after the <code>Cache-Control: no-cache</code> header? Tried to find a solution, though without any luck.</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.

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