Wrong Age header

Open const-t opened this issue 3 years ago • 3 comments

Looks like Age header calculates using Date header from backend, when backend returns incorrect Date Age also be incorrect.

How to reproduce: Respond to tempesta with incorrect Date with enabled caching on tempesta.

What is the correct calculation scheme for Age if Date from a backend is incorrect? Isn't this just a foot-shooting by the backend?

RFC 9110 6.6.1 says:

A recipient with a clock that receives a response with an invalid Date header field value MAY replace that value with the time that response was received

IIUC it's not necessary, however we can replace Date. Yes, it's foot-shooting, but in general we should know about such behaviour of tempesta.

For instance: Sat, 01 Oct 2022 7:19:16 GMT this date is incorrect. Hours specified without leading zero. Resulted Age is something like this Age: 1664612639.

OK, I see. This is the "MAY" feature - it'd be good to have this, but nobody will blame us if we don't do this, so I move this to backlog.
