That seems like quite a reasonable way of going about it. Many web a applications delete cookies be replacing them with one that is about to expire. The :max-age 1
syntax makes this look much more elegant than it does in, for example, Javascript.
In clojure/ring, how do I delete a cookie?

Question
Suppose I want to delete a cookie (for example, ring's session cookie):
Making a response map like this:
{:cookies {"ring-session" {:value "kill", :max-age 1}}}
seems to work, but it feels a bit hacky.
Is there a clean way to just delete it?
Solution
OTHER TIPS
I was using wrap-session and the other handlers in ring.middleware. Setting the cookie to max age was not working in the response since it was just being overwritten (very frustrating to diagnose!)
This is what I needed to do:
(defn clear-session! [resp]
(assoc resp :session nil))
ring
seems do not support this, but you can send the user agent a new cookie with an Expires attribute with a value in the past.
