nugget of code

Suppose you have a feature debug that you use to turn on debugging, and that if debug is on *features* you want to araneida not to cache your responses for a day. Then you can use the following code:

(araneida:request-send-headers

   request

   :content-type "text/html"

   ;; cache this page for 24h

   #-debug #-debug

   :expires (+ (get-universal-time) (* 60 60 24)))

The #-debug #-debug will exclude both expressions that follow. Another neat trick I've learned from Erik Naggum.
