Please help: Trying to set an exact time-to-live (override origin cache control) in Squid (2.4 STABLE6) configuration: ___ refresh_pattern 30_minutes_cache_control_url 15 0% 15 override-expire ignore-max-age Observed: URL is matched (in log), but objects still cached for 30 minutes, rather than 15, as hoped. ___ refresh_pattern 30_minutes_cache_control_url 60 0% 60 override-expire ignore-max-age Observed: URL is matched (in log), and objects are cached for 50-70 minutes (not exactly 60). ___ Q1: Does refresh_pattern only extend expiration? Is there a way to enforce an exact time-to-live (per URL) in Squid? Q2: Does refresh_pattern operate in +-10 minutes granularity? Why 60 minutes become 50 - 70? Thanks.
