              from <span class="vcard"><a class="email" href="mailto:joepeck&#64;webkit.org" title="Joseph Pecoraro &lt;joepeck&#64;webkit.org&gt;"> <span class="fn">Joseph Pecoraro</span></a>

        <pre>The Web Inspector frontend is only told about one requestWillBeSent from the backend (followed up by its responseReceived/dataReceived/loadingFinished updates):

    backend: {
        &quot;method&quot;: &quot;Network.requestWillBeSent&quot;,
        &quot;params&quot;: {
            &quot;requestId&quot;: &quot;0.15&quot;,
            &quot;frameId&quot;: &quot;0.1&quot;,
            &quot;loaderId&quot;: &quot;0.5&quot;,
            &quot;documentURL&quot;: &quot;file:///Volumes/Data/Users/pecoraro/Desktop/cache-bug.html&quot;,
            &quot;request&quot;: {
                &quot;url&quot;: &quot;<a href="http://api.randomuser.me/">http://api.randomuser.me/</a>&quot;,
                &quot;method&quot;: &quot;GET&quot;,
                &quot;headers&quot;: {
                    &quot;Accept&quot;: &quot;application/json, text/javascript, */*; q=0.01&quot;,
                    &quot;User-Agent&quot;: &quot;Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11) AppleWebKit/602.1.1 (KHTML, like Gecko) Version/9.0 Safari/601.1.41&quot;,
                    &quot;Cache-Control&quot;: &quot;max-age=0&quot;
                }
            },
            &quot;timestamp&quot;: 0.045744980983727146,
            &quot;initiator&quot;: { ... }
            &quot;type&quot;: &quot;XHR&quot;
        }
    }

So from the appearance of the frontend only 1 request was sent. That may in fact be what the engine is doing. The frontend should at least show that &gt;1 XHR was initiated for the same URL, even if only 1 request was actually sent and they are sharing it. It would likely share a lot of timing information.</pre>
