title: Bizarre Error in Chrome Developer Console - Failed to load resource: net::ERR_CACHE_MISS
body: <p>As far as I can tell, this error was not being thrown yesterday on Chrome, and as of this morning, it is. I have not changed any of my browser settings. I have attached a screenshot (after opening/closing Developer Tools window four times):</p>

  <p>This issue is tangentially similar to Stack Overlow post <em><a href="https://stackoverflow.com/questions/4390134">Failed to load resource under Chrome</a></em> except that it only occurs when I "Inspect Element" in Chrome. Here are the details I have:</p>
  
  <p>To the best of my ability I undid everything I did since last night (when I did not have this error) and the error persists. When I remove all pre-<code>&lt;html&gt;</code> <a href="http://en.wikipedia.org/wiki/PHP" rel="noreferrer">PHP</a> code, the error disappears.</p>
  
  <p>When I only remove all the pre-<code>&lt;html&gt;</code> PHP code except </p>
  
  <pre><code>&lt;?php session_start(); ?&gt;
  </code></pre>
  
  <p>the error returns.</p>
  
  <p>Since the error seems to involve PHP, I checked my error log, but there are no notices, warnings, nor errors. When I close the Developer Tools window and then open up the window without a page reload, the number of errors increments by one each time.</p>
  
  <p>When I keep the window open, and then reload the page, the page reloads without throwing the error. However, as soon as I close the Developer tools window again, then open it (no page reload), the error is thrown. I checked my site on Firefox with <a href="http://en.wikipedia.org/wiki/Firebug_%28software%29" rel="noreferrer">Firebug</a> enabled, and no errors are thrown, making it seem like a Chrome issue (version 38). My site seems to function normally otherwise. Other sites on device browsed via Chrome (for example, Yahoo) also experience this error.</p>
  
  <p>Also, I have not manually changed any of my browser settings since months ago. As an additional note, this is the <strong>second strange error I have encountered in Chrome</strong> in the last year (see Stack Overflow question <em><a href="https://stackoverflow.com/questions/23725085">Failed to load resource: net::ERR_NETWORK_IO_SUSPENDED</a></em>), to which no one was able to find a solution, even with a bounty offered.</p>
  
  <p>Is there a way to prevent this error, or is this a browser-only issue? On a side note, when I open up Developer Tools in Chrome for Stack&nbsp;Overflow, there is no error thrown, so either Stack&nbsp;Overflow is not coded in PHP or they have a way to prevent this error. I think my site is not affected, but I am not 100% sure, and it makes me nervous :)</p>
