Every site should have a script like web.archive.org/__cleancookies__.html
Posted by jpluimers on 2021/06/02
I run in too many sites that keep creating new cookies, but never delete the old ones, ultimately leading to 5xx errors.
Every site should have a page like [WayBack] web.archive.org/cleancookies.html that cleans non-current cookies.
So I copied toe source to [WayBack] Copy of https://web.archive.org/cleancookies.html · GitHub for inspiration to look at.
