[Backport 8.x] Update ca_last_update/crl_last_update on HTTP 304#526
Merged
Conversation
A 304 Not Modified response confirms the local CA certificate or CRL is current, so the refresh-interval TTL should be reset. Previously ca_last_update (backed by ca.pem's mtime) never advanced past the initial download in steady state, so every agent run saw a stale mtime and re-issued the conditional GET regardless of ca_refresh_interval. The CRL path had the same structural issue but was latent because CRL endpoints typically respond 200 often enough that save_crls bumps the mtime naturally. Fix it for symmetry. Fixes #435 Signed-off-by: SAY-5 <say.apm35@gmail.com> (cherry picked from commit b262f75)
