Request Monitoring in Chrome

I know this is an old thread but I thought I would chime in.

Chrome currently has a solution built in.

1. Use CTRL+SHIFT+I (or navigate to Current Page Control > Developer > Developer Tools. In the newer versions of Chrome, click the Wrench icon > Tools > Developer Tools.) to enable the Developer Tools.
2. From within the developer tools click on the Network button. If it isn't already, enable it for the session or always.
3. Click the "XHR" sub-button.
4. Initiate an AJAX call.
5. You will see items begin to show up in the left column under "Resources".
6. Click the resource and there are 2 tabs showing the headers and return content.

The most up-to-date answer to this is: they are listed under the 'Network' button in the developer tools, no longer under 'Resources' like it used to be.

Update

Chrome changed how to inspect requests and suggests now to use the Catapult Netlog Viewer with the logs exported from chrome://net-export/
