No, MapServer doesn't cache WMS GetMap responses, but you could likely 
use a regular Web caching proxy to do that. For instance, I have heard 
of people using Squid as a caching proxy for regular website in the past.

Note that the order of parameters in a WMS GetMap request may vary 
depending on the client that generates the request, and this means that 
two requests for the same map, but in which the GetMap parameters are in 
a different order, may not be detected as being identical by a web 
proxy. However, multiple requests coming from the same client (e.g. all 
requests from gvSIG) should all use the same ordering and all be cached 
efficiently by a proxy.
