--------------------------------
Summary: cache.config clarification
Key: TS-2429
URL: https://issues.apache.org/jira/browse/TS-2429
Project: Traffic Server
Issue Type: Improvement
Components: Documentation
Reporter: Miles Libbey
The cache.config doc could use some clarification:
- It is not clear to me what the difference between pin-in-cache and
ttl-in-cache is -- when would you use one instead of the other. For instance,
a clarifying remark might be,
- 'Use pin-in-cache when you just want to override the server's TTL' or
- 'Use pin-in-cache when you want to make sure all the requests for a domain
are not evicted' or
- 'use ttl-in-cache when a domain is not setting cache directives, but you
want to cache anyway'
- It's not clear to me when 'revalidate' would kick in. Does it only apply to
objects that have cache-control headers?
- I'd find it useful to have a few more combinations of examples:
{don't know if these are valid syntax}
# force a specific regex to be in cache between 7-11pm of the server's time.
url_regex=example.com/articles/popular.* time=19:00-23:00 ttl-in-cache=1d2h
# force all requests that would be sent to myorigin.com from 192.168.0/24 to
not be cached
dest_host=myorigin.com src_ip=192.168.0/24 action=never-cache
