Web cache proxy for Isp

Hi Guys
We have a isp(internet service provider) about 100Mb BW
We are currently using Web proxy Mikrotik (CHR)
But Web proxy has a several problem.
1-It doesn’t Cached When The user Download with internet download manager (Multi session)
2-The option is not the amount of RAM used (chr Ver 6.4.8)

I think These are problem Web proxy.

Caching proxies in 2021 with most websites running TLS nowadays, is… oxymoron.

Web Caching proxy tools still exist in 2021? Crazy.

I think you are Wrong

The Most Update Servers are Http Protocol.

What about squid/nginx/varnish?

Squid-Cache is the general solution for http/1.x .
If you have a specific service you want to cache there might be a solution for this specific issue.
What do you need it for? windows updates?

Multi session download method of Download manager might not be compatible with just any webproxy cache.
