Yes I tried that and I saw that traffic still create a big file for cache called cache.db
And writes a lot to host.db in the same directory

Sounds like you retained the default cache (in storage.config), it will create that regardless if HTTP caching is enabled or not (you can still use it for e.g. plugins to read/ write things to cache). Just make sure storage.config is empty and you would definitely get no cache file.

The HostDB stuff is the DNS cache. It’s as expected that it’ll write to that, you can turn off the writes, but that works very poorly in ATS v6.x, but should be improved in v7.0.0.

Maybe I don’t test it right?

Have you tried to set 0  to  CONFIG proxy.config.http.cache.http  in  /usr/local/etc/trafficserver/records.config.
as follows: CONFIG proxy.config.http.cache.http INT 0

Hi All,
I search for almost a day and couldn’t find how can I disable cache in trafficserver for all traffic.
Our system use trafficserver as proxy to scrap remote sites so we don’t need/want any kind of cache
Thanks and Sorry I couldn’t find that
