- Use SameSite=Strict to avoid issues in modern browsers & prevent
session-stealing attacks
- Use Secure when requests run over HTTPS by default to avoid
downgrade-based session-stealing attacks
- Add warning for PHP <= 7.2, as it doesn't support SameSite in
setcookie().
The BkTree tester gave me the idea.
No longer will you have to hope that search indexing will complete in
time and adjust the maximum execution time for larger wikis..... when
that's implemented.
