Some browsers have implemented a version of the not-yet-standard, Resource Timing API where you can collect some of this information.

Some browsers may have some of this info available to browser extensions as part of their developer tools support, but that would require the installation of a custom extension, not something that could be done from a regular web page.

For very specific operations where you control the calling code or you know the calling code, it is possible to instrument some things. For example, if you know that all ajax calls go through one particular function, you can hook that function and it's completion handlers and monitor all ajax calls.

You can use Resource Timing API to get all relevant information (domain lookups, cache hits, redirects, etc.) about each resource being loaded on your website.

You can read about it here. There is also a bookmarklet that generates a page load waterfall using this API.

Resource Timing API is available in Chrome, Chromium, Chrome Mobile and IE10. Firefox team seems to be working on it.
