Issues with valid Dynamic REGEX

[tssrshot]

I've gone around the axle trying to teach myself, so i'm calling uncle a little:

I cannot get the following dynamic squid config to validate:

refresh_pattern ([^.]+.|)(download|adcdownload).(apple.|)com/.*\.(pkg|dmg) 4320 100% 43200 reload-into-ims;

refresh_pattern ([^.]+\.)foreflight.com/.*\.(zip|sqlite|sl|pdf|png|jpg|gif|fbtiles) 4320 100% 86400 reload-into-ims;

refresh_pattern ([^.]+\.)simperium.com/.*\.(zip|sqlite|sl|pdf|png|jpg|gif|fbtiles) 4320 100% 86400 reload-into-ims;

refresh_pattern ([^.]+\.)segment.io/.*\.(zip|sqlite|sl|pdf|png|jpg|gif|fbtiles) 4320 100% 86400 reload-into-ims;

The Apple one works, but the three below don't!  Although I can't find the difference.

Thank You,

Bryan
