Unfortunately, that sort of thing isn't possible with JSTL. If you look at 
the definition of the <c:set> tag, you'll see that the "var" attribute 
cannot use a request-time value. In other words, it can only use a string 
literal. Probably the best thing to do would be to create an EL function 
for this sort of thing. See the JSP 2.0 spec section "JSP.2.6 Functions".
