1729	If-Modified-Since won't trigger 304 unless server send Last-Modified	ayghor@…		"I just realized that if I make a request with a '''If-Modified-Since''' that would cause a '''304''' but the server is set to '''add_header Last-Modified """";''', it will trigger a '''200'''.

I'm not sure this is intended, as the server doesn't need to tell the client when the document was last modified in order to decide between '''304''' or '''200'''."	defect	closed	minor		nginx-core	1.14.x	invalid	cache, 304, If-Modified-Since, Last-Modified		Linux preview-webserver-i-0133ab3a1c12cf7d2 4.15.0-1029-aws #30-Ubuntu SMP Wed Nov 21 23:58:13 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux	"nginx version: nginx/1.14.0 (Ubuntu)
