    <p>What is the difference between a HTTPS request sent via node.js module and via XMLHttpRequest?</p> <p>I am trying to send a HTTPS GET request to amazon aws to get a security token from javascript (XMLHttpRequest) and it always fails with "Origin <a href="http://my_ip" rel="nofollow">http://my_ip</a> is not allowed by Access-Control-Allow-Origin", but if I send same HTTPS GET request via a node.js module it works fine.</p> <p>I am confused of this because if server does support CORS, any request from any where should fail, but it goes through via node.js, but not via XMLHttpRequest. </p> <p><strong>This FAILS</strong></p> <pre><code>var url_ = "https://sts.amazonaws.com/?Action=GetSessionToken" + "&amp;DurationSeconds=3600" + "&amp;AWSAccessKeyId=XXXXXXXXXXXXXXX" + "&amp;Version=2011-06-15" + "&amp;Timestamp=" + encode(timestamp) + "&amp;Signature=" + encode(hash) + "&amp;SignatureVersion=2&amp;SignatureMethod=HmacSHA256"; // Simple GET request $.get(url_, function(data) { alert("response: " + data); }); </code></pre> <p><strong>This WORKS</strong></p> <pre><code>var https = require('https'); var options = { host : 'sts.amazonaws.com', method : 'GET', path : '/?Action=GetSessionToken' + '&amp;DurationSeconds=3600' + '&amp;AWSAccessKeyId=XXXXXXXXXXXXXX' + '&amp;Version=2011-06-15' + '&amp;' + timestamp + '&amp;' + signature + '&amp;SignatureVersion=2&amp;SignatureMethod=HmacSHA256' }; https.get(options, function(res) { res.on('data', function(d) { process.stdout.write(d); }); }).on('error', function(e) { console.error(e); }); </code></pre> <p>Can anyone explain me how this works?</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.
