Parent-child-child caching issue
Hi all,
I am using parent-child heirarchy caching for hls and dash.
main parent(172.16.0.40) middle-child(172.16.6.5) end-child(172.16.48.20)
the device which is connected to the end-child is accessing the url
http://host1.domain.com/hls/channel/index.m3u8
in the endchild:
proxy.config.http.cache.http INT 1
remap_required INT 0
reverse_proxy.enabled INT 0
but written the following rule in remap.config
map http://host1.domain.com http://host1.domain.com
@plugin=/opt/ats/libexec/trafficserver/regex_remap.so
@pparam=/tmp/regex1.config @pparam=no-query-string
[root@lmo-aphy00038 trafficserver]# cat /tmp/regex1.config
^/(.*)$ http://host1.domain.com/$1
parent.config
dest_domain=host1.domain.com method=get parent="172.16.0.40:80"
go_direct=false
in mid_child:
proxy.config.http.cache.http INT 1
remap_required INT 0
reverse_proxy.enabled INT 0
remap rule
map http://host1.domain.com http://host1.domain.com
@plugin=/opt/ats/libexec/trafficserver/regex_remap.so
@pparam=/tmp/regex1.config @pparam=no-query-string
parent.config
dest_domain=host1.domain.com method=get parent="172.16.0.40:80"
go_direct=false
in main parent
remap file enabled
reverese proxy enabled
caching enabled
map http://host1.domain.com/ http://172.16.200.102/
@plugin=/opt/ats/libexec/trafficserver/regex_remap.so @pparam=
@pparam=no-query-string
[root@bangalore trafficserver]# cat /tmp/jitp1.config
^/(.*)$ http://172.16.200.101/$1
101 server has following http headers:
Access-Control-Allow-Origin: *
Cache-Control: max-age=10
the issue is none of the servers are caching the content.
is the implementation logic is right?

I think you need to break the problem down. Start from the parent that is closest to the origin and make sure that is caching the way that you want, then work up through the cache hierarchy. At each step, I'd use server los and the xdebug plugin to make sure that the cache behaviour is what you want.
