Again using JSTL (Servlet 2.3 / JSP 1.2 container is required), you can
use the "||" operator to implement an OR:
<c:if test="${(foo == '1') || (foo == '2')}"/>
... stuff when foo is 1 or 2 ...
</c:if>
The expression language in JSTL 1.0 (and also in JSP 2.0, where you can
even use it in template text) is likely to become a JSP page author's best
friend. But if you're stuck on a Servlet 2.2 / JSP 1.1 based server,
you're best bet is probably to write your own custom tag that implements
the test you are after.
