What is the difference between a transparent proxy and a regular one?

Question

Squid

and will such proxying be transparent if you wrap all traffic from port 80 to port 3128?
Or will such proxying be normal, with the difference that it will not be necessary to prescribe proxies on clients in browsers?

Answer 1

This will be transparent proxying.
That is why it is called transparent, because. happens "transparently" for the user, i.e. without changing settings on its side.
