bypassing cache in cache.config

[Mohd Akhbar <my...@gmail.com>]

Hi,

I try to exclude some streaming site (f4f, i think its flash) from
being cache by ATS. So, i add these 3 line in cache.config. How do i
know if these site really bypass the cache ?

dest_host=host1.akamaihd.net action=never-cache
dest_host=host2.akamaihd.net action=never-cache
dest_domain=akamaihd.net action=never-cache

If above lines work, why is my video stop after sometime whenever i
enable the disk caching ? I'm using the default one in storage.config
(var/trafficserver 256M) and by the way log from cache says 'cache
enabled' as in diags.log

[May 19 14:34:07.272] {0x2b3b051dd8c0} STATUS: opened

Fyi, my ATS is using parent proxy which is a squid. I'm quite certain
this is not an issue because if i disable the disk cache in
storage.config then the streaming is fine.

Thank you.

Mohd,

I would use curl with the --header 'Cache-Control: Only-If-Cached' to test it. That will retrieve the URL from ATS only if it is cached.
