Last weekend our server/app got bugged and some of your visitor are now getting Error 400 Bad Request everytime they visit our website.
I know this error was caused by malformed cookies and everything goes OK when the visitor manually clears browser cache, BUT...
Is there anyway I can force it to be cleared using PHP?
I had tried setting header('Clear-Site-Data: "cache", "cookies", "storage", "executionContexts"'); as first line in all files, but it didn't worked as the error is fired first =(
