It's called "server-side includes", and it's relatively standard if you're
using Apache. You have to have the directory you want to have server-side
includes enabled in with a config stanza kind of like so:

<Directory "/var/www/localhost/htdocs">
Options Indexes FollowSymLinks Includes
</Directory>
# note that Includes is the option you want to have enabled for this dir.
# that's the docroot of my webhost; modify for your setup
# make sure to restart apache if you change the config file

Once this has been done, all you have to do is to put a construct like so into
foobar.html:

<!--#include virtual="/incs/nav.html" -->

...this tells apache that when it's reading foobar.html, it should read the
file /var/www/localhost/htdocs/incs/nav.html and insert that file's contents
into foobar.html at that point, before sending stuff to the client.[0] This
is *really* useful. At work, we basically depend on apache SSI to do 5 tons
of stuff, since many pages use the same stuff across the whole site for
navigation/menu bars/whatever.

If this didn't make any sense, holler.

[0] It can get a bit more complex than that, what with RewriteRules and other
stuff, but that'll get you started.
