There is a local caching mechanism, although it does not operate the
same way as a classic browser. Caching directives sent in the HTTP
response are ignored. Individual scripts instead control the cache use
with options like "bypass_cache" (meaning "I want a fresh response") or
"no_cache" (meaning "Do not cache my request").

For details take a look at the NSE documentation at
https://nmap.org/nsedoc/lib/http.html

If you do see a case where subsequent requests should be fulfilled from
the local cache but they are not then please document it as an issue at
GitHub: https://github.com/nmap/nmap/issues
