I tried using ATS 4.1.2 but it doesn't work, maybe it's implemented into later
versions like 4.2. I am waiting for its availability in the ports tree under
FreeBSD.

OK.
I want to keep objects like media (avi|jpg|mp3) for 7 days in cache while
telling the client "max-age=3d", keep office file for 3 days in cache while
telling the client 1 day (using ATS 4.1.2 TTL are in seconds)
First I use cache.config
url_regex=.* suffix=avi,mp3,jpg ttl-in-cache=7d
url_regex=.* suffix=doc,xls,ppt ttl_in-cache=3d
Then I want to use remap.config
regex_map www.domain.com http://10.10.16.3 @plugin=header_rewrite.so
@pparam=/usr/local/etc/trafficserver/header_rewrite_media.config
And header_rewrite_media.config
cond %{SEND_RESPONSE_HDR_HOOK}
cond %{PATH} "/(avi|mp3|jpg)$/"
rm-header Cache-Control
add-header Cache-Control max-age=3d
cond %{PATH} "/(doc|xls|ppt)$/"
rm-header Cache-Control
add-header Cache-Control max-age=1d
I can't get it to work. Most of CDN offer this kind of granularity but I don't
find how to it with ATS.
