title: Detecting "Connection was Reset" in an iframe
body: <p>I work on a long-running application that gets deployed in chrome in kiosks with arbitrarily bad connectivity. It's a standard web-app, and we serve various kinds of content into these kiosks, sometimes using iFrames to load fairly complex interactive assets.</p>
  
  <p>Every once in a while, we see that the interactive asset simply displays a chrome error, "the connection was reset", as the content of the iframe.</p>
  
  <p>Is there any way for me to listen for this error in the parent application, so that I can know when an interactive asset has failed to load due to bandwidth or whatever? </p>
  
  <p>There are try/catches around the content to handle errors thrown by the running interactive asset, but if it never even loads this apparently doesn't trigger those errors.</p>
  
  <p>Anyone got any bright ideas? :)</p>
