[GitHub] [trafficserver] stackexpress-jawed opened a new issue #8216: The Prefetch Plugin is not working
stackexpress-jawed opened a new issue #8216:
URL: https://github.com/apache/trafficserver/issues/8216
I am using Prefetch Plugin as per this doc - https://docs.trafficserver.apache.org/en/9.0.x/admin-guide/plugins/prefetch.en.html
But It’ not prefetching the objects.
Prefetch Pattern - `--fetch-path-pattern=/(.*-)(\d+)(.*)/$1{$2+1}$3/`
Prefetch Plugin Logs (confirms that plugin is loaded successfully)
