Yes I agree , I have reviewed code and test again.

I don't know what the "bug" is. Maybe this is a feature? I confess I've been away from this project for quite some time and haven't looked closely at cookies before. Do you know if other proxies do this cookie path re-mapping? That's what I'd call it based on what I gleaned in your diagram but I may misunderstand.

Yes, you can think of it as a feature. The purpose of this feature is to cache proxy cookies But I think this is to further improve the cookie mechanism The role of proxy cookies is not lost. The cookie of the proxy service is invalid in the previous version without modification. At present, we use the modified one, and it has been running on our server for a long time. And I designed this mechanism as optional. Only valid when docacherootpathcookies is true. The default is false
