I’m not entirely sure as this isn’t something I’ve encountered before, but have done a little more research and will do my best to provide some suggestions.
If you have the Firefox browser, I’ve found that they do a pretty good job with displaying expiry dates in their developer tools “Storage” section rather than just a string of numbers. This will give you some idea how long the cookies persist for (best to clear cookies on a “blank” page before browsing so they can be set fresh). They still have generic names, though, so additional research is needed.
If you use a site like Cookiepedia you can use the drop-down in the upper-right corner of the page, change it from “Website” to “Cookie” and then input the cookie name, it will give you more information about the cookie and what it does.
Some of the cookies you list above appear to be tied to ordinary things like Google Analytics, and some like VISITOR_INFO1_LIVE and YSC are tied to specific applications like YouTube. SAPISID is used by the DoubleClick ad network.
So, it does take some work but the data can be gathered. Thankfully you aren’t working with a very long list ??
Best of luck! Let me know how it goes!
If this solves your issue please be sure to mark it “resolved.”
