Lynx currently only has a *memory* cache, and it keeps some documents
in memory only in an alread-parsed form.  It seems what you want is 
a persistent disk cache.

Such cache programs already exist.  They operate as a HTTP proxy server
(or gateway).

Lynx supports proxies (like every browser that I know of).  
Once you have a caching proxy installed and configured, all that remains
to do is configure Lynx to use it, see lynx.cfg.

I would start with the CERN httpd server.  Documentation and the program
itself are available from www.w3.org.  Installing it (and, in the prcess,
reading the documentation) should answer your questions.

I am sure there are also other freely available proxy caches yhat you
could use.  (Squid?)

Btw, I am running a CERN httpd proxy on linux.  It works.
