2342	Setting a very high max-age value for Cache-Control causes int overflow	hyphenized@…		"When proxying to a ruby on rails application, it is possible to receive 100 years (in seconds) as the max age value for the purpose of caching the response forever. In such cases, when nginx parses the value, it ends up being negative thus marking all cache responses as `EXPIRED`.

According to the spec[https://datatracker.ietf.org/doc/html/rfc7234#section-1.2.1] 
{{{
   the cache must consider the
   value to be either 2147483648 (2^31) or the greatest positive integer
   it can conveniently represent
}}} 


I think the issue might be somewhere near https://github.com/nginx/nginx/blob/master/src/http/ngx_http_upstream.c#L4761 ."	defect	closed	minor		nginx-core	1.19.x	invalid			Tested on Windows	nginx version: nginx/1.20.2
