title: Suppress Chrome 'Failed to load resource' messages in console
body: <p>I'm writing a script that uses an XMLHttpRequest to search for a file defined by a relative path, by attempting to resolve that relative path against other same domain absolute paths that the script is aware of, then attempting to load the file from that resolved url. If I encounter a 404, I just try to resolve the files relative path against another absolute path, and try again. For this particular script, its perfectly fine to encounter a 404- however, my console is littered with 'Failed to load resource: the server responded with a status of 404 (Not Found) messages, and I want to suppress them.</p>
  
  <p>There is no error to catch as far as I can see- error cases are handled by the xmlHttpRequest.onreadystatechange handler, and there is no window.onerror.</p>
  
  <p>Is there any way to suppress these messages?</p>
  
  <p>Thanks</p>
