I'm out of ideas sorry.


FWIW: this is what I get from my test setup using your refresh_pattern:

1496766607.433   1284 ::1 TCP_MISS/200 16628 GET 
http://qthttp.apple.com.edgesuite.net/1010qwoeiuryfg/0150_vod.m3u8 - 
HIER_DIRECT/119.224.143.41 application/x-mpegURL
1496766610.254    902 ::1 TCP_REFRESH_UNMODIFIED/200 16499 GET 
http://qthttp.apple.com.edgesuite.net/1010qwoeiuryfg/0150_vod.m3u8 - 
HIER_DIRECT/119.224.143.41 application/x-mpegURL

I am currently testing Squid-4.0.20, but it should behave the same in 
the recent few v3.5 releases.
