While Karl's suggestion to use relative links is right on, you have to watch out for
a couple of gotchas. The one that always bites me is, "who is interpreting the
relative URL?"
In this particular case at hand (creating a hyperlihk), what you really need to do
is:
<a href="foo.jsp">Link-to-Foo</a>
without the forward slash, because this relative link is resolved by the browser.
If you were using <jsp:include> or <jsp:forward> (which is resolved on the server
side), you would indeed need the slash.

For the record, request.getContextPath() will return you the "/APP-NAME" part of the
path when you are running under a servlet container compatible with the 2.2 API spec
(such as Jakarta Tomcat). This can be very useful when you need to dynamically
construct absolute URLs for pages within your application.
