I know this is an old thread but I thought I would chime in.
Chrome currently has a solution built in.
- Use
CTRL+SHIFT+I
(or navigate toCurrent Page Control > Developer > Developer Tools
. In the newer versions of Chrome, click the Wrench icon > Tools > Developer Tools.) to enable the Developer Tools. - From within the developer tools click on the
Network
button. If it isn’t already, enable it for the session or always. - Click the
"XHR"
sub-button. - Initiate an
AJAX call
. - You will see items begin to show up in the left column under
"Resources"
. - Click the resource and there are 2 tabs showing the headers and return content.
