Please take extreme care with the use of ignore-private, ignore-no-store, and override-expire on content to/from those systems. I have seen and heard about medical screwups (wrong prescriptions, wrong diagnosis, and patient record mixups) caused by proxies caching medically relevant information in direct contravention of the cache control headers emitted by medical related software. The .tif* and .bin file formats in particular are used for some medical scan data due to resolution quality. > 2014/05/01 15:08:21| Processing: refresh_pattern -i \.index.(html|htm)$ 0 40% 10080 > 2014/05/01 15:08:21| Processing: refresh_pattern -i \.(html|htm|css|js)$ 1440 40% 40320 > 2014/05/01 15:08:21| Processing: refresh_pattern . 0 40% 40320 > 2014/05/01 15:08:21| WARNING: use of 'override-expire' in 'refresh_pattern' violates HTTP > 2014/05/01 15:08:21| WARNING: use of 'ignore-no-store' in 'refresh_pattern' violates HTTP > 2014/05/01 15:08:21| WARNING: use of 'ignore-private' in 'refresh_pattern' violates HTTP > Amos
