Browsing web pages without a live TCP/IP network connection

If you want to be able to use Netscape Navigator offline so you can
browse web pages without a live network connection, then the most
straightforward way to do this would be to make your cache very large
(by bumping up the "Cache Size" setting in the Netscape Preferences),
set "Check Documents" to "Never" (also in the Preferences), and visit
every page you'll want to see later so that those pages will get copied
into the cache.  (Note that imagemaps won't work this way, because
imagemaps are processed by the web server itself, so just watch out for
what you click.)
If you just want to use Netscape Navigator to view HTML files on your
own hard drive, then there's no special preparation necessary; you don't
need to worry about caching.  Just start up Netscape Navigator and use
"Open File" under the File menu to load in your local pages.
There is one caveat, however: The X and Macintosh versions of Netscape
Navigator are perfectly happy to start up without networking software
loaded (although they may complain a little bit), but the Windows
version will not start up at all unless it can find a "WINSOCK.DLL"
file.  To work around this problem, obtain the file "MOZOCK.DLL" from
"ftp://ftp.netscape.com/unsupported/windows/", rename your copy of it to
"WINSOCK.DLL", put it into your WINDOWS\SYSTEM directory, then restart
Windows.
