Hi,
I would like to know if the web proxy in routerOS is based on squid or some other linux or custom linux package.
We were having a discussion here at work and we could not find an answer !
Cheers.
A quick search of the forums shows that Mikrotik wrote their own proxy program. They do not use squid.

“it was squid in 2.9.x, 3.x uses mikrotik proxy 
”
Well that answers that !
Cheers
