I tried to enable the prefetch functionality in my apache traffic server .
I followed the steps suggested in prefetch config file .
1. added
CONFIG proxy.config.prefetch.prefetch_enabled INT 1
in records.config .
2. uncommented prefetch children and gave my ip .
3. uncommented those default tags in the end
I tried with traffic server 3.2.0 and it seemed to be working fine .
right now I m using Apache Traffic server 3.3.4 developers version.
now this is the log and back trace i m getting after running traffic server
with these configurations.
