The "HTTP Cache" manager sets HTTP cache headers for requests.
This allows external HTTP caches (usually, there is one in
the browser; there may be caches in between, either set up by
yourself or another).

Unless you use high end features of Squid, the HTTP cache approach
can only cache complete requests.


A RAM Cache can cache page components (i.e. it has smaller
granularity than the HTTP Cache approach).


Thus, you use an "HTTP cache" to cache complete requests
and a "RAM cache" to cache pieces that are combined into
full pages by some non cached device...
