HTTP-Request - Missing response - net_error = -3 (ERR_ABORTED)
<p>I'am using a <strong>RESTful API</strong> with <strong>CORS</strong>. Sometimes (can't reproduce when/why it happend) a AJAX-Request is aborted by the client and no response comes up. This happends not only in chrome, also other browser are effected. I tried debugging a lot and searched a lot for a solution, but I didn't find one right now. All the requests were procceed by the server were well, only the reponse is <strong>blocked</strong> <strong>by</strong> <strong>client</strong>. </p>

<p>The following is a <code>chrome://net-internals/#events</code> based on the request which is aborted by error<code>net_error = -3 (ERR_ABORTED)</code>. Mostly this problem comes up while using SSL, but SSL is not in use. </p>
