Is there a way to view the creation source of a cookie in Chrome?

Question

I have been using the Chrome dev console's Application tab to look through various cookies stored by some sites. But one key piece of information that seems to be missing is a log of what actually created the cookie (i.e. where it came from).

Is there some tool in Chrome that will show me where a cookie actually came from (eg: javascript filename + line of code, set-cookie response header, etc)?

Answer 1

If it's set in a HTTP response header, you can search for Set-Cookie in the Network panel's search UI.

Press Command+F or Control+F to open that search box.

You can search across all text by pressing Command+Shift+F or Control+Shift+F and then typing document.cookie into the Search tab, which is at the bottom of the next screenshot. If you know the name of the cookie, it would probably be more straightforward to search for that, instead.
