    <p>I'm working on an RSS aggregator via node-webkit, and I've stumbled upon an issue where a seemingly random volume of my requests (code below) will fail with any of the following errors: HPE_INVALID_CONSTANT, ETIMEDOUT, EAGAIN, and HPE_INVALID_HEADER_TOKEN. I've sorted those in regularity of occurrence.</p> <p>I made a test.html file with as much relevance as possible. Just plug in a large volume of web page urls into <code>httpList</code> and it will work. though, be careful what URLs you use, you wouldn't want to crash someones server! A list of around 56 seems to work for causing the errors.</p> <p>As an aside, this is really hard to reproduce, meaning its gotta be something I can change on my end. Sometimes the same URL will fail, while on the next pass it will work. Also I have had URLs that have failed, that were indeed accessible (I opened them up in chrome no problem).</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;title&gt;HTTP Get test&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;script&gt; var httpList = []; var fromUrl = function(stringUrl) { var http = require('http'); var url = require("url"); var urlData = url.parse(stringUrl); var parser = window.document.createElement('a'); parser.href = stringUrl; var options = { host: urlData.host, path: urlData.path + urlData.search + urlData.hash }; var httpResponse = function(response) { response.setEncoding('utf8'); request.setSocketKeepAlive(true); var str = ''; response.on('data', function(chunk) { str += chunk; }); response.on('end', function() { request.setSocketKeepAlive(false); console.log("url",stringUrl,"was successfully parsed"); }); } var request = http.request(options, httpResponse) request.on('error', function(e) { if (e.code === "ENOTFOUND") { console.error("The feed", stringUrl, "could not be fetched.") } else { console.log(e, e.message, stringUrl); } }); request.end(); }; for(var i=0;i&lt;httpList.length;i++) { fromUrl(httpList[i]); } &lt;/script&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

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.
