Hello ,
i’m new with MikroTik i was configuring it on a pc , everything worked well , but one more thing , i need to configure the cache service , i was wondering if it needs a special package or if i can have any tutorial , and i have no idea about the proxy and transparent proxy to enable it or something , hope i can get some support about the requirement what to do to enable cache ,
THANKS A LOT
Proxy is included to system package.
