Displaying compressed files (such as "foo.html.Z")

Netscape Navigator on Macintosh and Microsoft Windows doesn't
automatically uncompress and display ".Z" and ".gz" files.  For example,
if you compress your web pages and put ".html.gz" and ".gif.gz" files on
your server, Netscape Navigator will download those files and open then
with an uncompressor program rather than displaying them, which is
probably not want you wanted to have happen.
In other words, Netscape Navigator deals with ".gz" and ".Z" files just
like it does with any other file it can't handle internally -- it
downloads them and opens an external program for them, if you've
configured one in the Netscape preferences.  It's just not clever enough
to notice if the uncompressed files are ".html" and ".gif" and display them.
However, Netscape Navigator on Xwindows *does* automatically display
compressed files properly, because all this involves on Unix is simply
adding "gunzip" or "uncompress" to the end of a pipe.
