Ring session middleware and compojure

I wanted to add session support to my web-application written in Clojure+Ring+Compojure.

Searching from google I found information how to use sessions using ring.middleware.session. However the examples would not work as is when your are using Compojure.

The complete code is presented below - main points:

on line 13 we use the compojure destructure format to extract session information from request to a value
on line 14 we read the key :count from the session map, if not found we will give it a default value of 0
on line 15 we increment the count with one and add to the session map
on line 18 we add the modified session to be sent with the response
