The logging entry in chrome’s console is a behaviour of chrome when any HTTP request is handled, not a problem with jQuery or ajax(XMLHttpRequest), even an <img>
or <link>
tag could cause this issue.
Your only choice is to fix your server-side code not to trigger an error for ajax (eg. 404 not found or wrong content-type), so based on the content logged to console, maybe a better solution could be found, please provide accurate logging message in your console.
