    <p>I have written a Servlet that should act like a web-proxy. But some of the Javascript GET calls only return part of the original content when I am loading a page, like <code>localhost:8080/Proxy?requestURL=example.com</code>.</p> <p>When priting the content of the java script to the console, they are complete. But the response at the browser is truncated.</p> <p>I am writing like this:</p> <pre><code>ServletOutputStream sos = resp.getOutputStream(); OutputStreamWriter writer = new OutputStreamWriter(sos); .. String str = content_of_get_request .. writer.write(str); writer.flush(); writer.close(); </code></pre> <p>The strange thing is, when I request directly the Javascript that was loaded during the page request like this:</p> <pre><code>localhost:8080/Proxy?requestURL=anotherexaple.com/needed.js </code></pre> <p>The whole content is returned to the browser.</p> <p>It would be great if someone had an idea. Regards</p> <p>UPDATE:</p> <p>The problem was the way how I created the response String:</p> <pre><code>while ((line = rd.readLine()) != null) { response.append(line); } </code></pre> <p>I read one line from a Stream and appended it on a StringBuffer, but it appears that firefox and chrome had a problem with that. It seems that some browsers implement a maximum line length for JavaScript, however there is no maximum line length mentioned in the RFC HTTP 1.1 standard.</p> <p>Fix:</p> <p>Just adding a "\n" to the line fixes the issue.</p> <pre><code>response.append(line+"\n"); </code></pre>

    1. COPerhaps you need to `flush()`and `close()` the writer? Are you doing that? [Javadoc](http://docs.oracle.com/javase/7/docs/api/java/io/Writer.html#flush%28%29)

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).
