@singhamritpal49 you will need to read the cookie somehow, and then pass it to the request. I would do it from the controller level, and then pass it as a request parameter.
Here’s a namespace that you can use to read / write cookies
which is using the goog.closure integration https://github.com/reagent-project/reagent-utils/blob/master/src/reagent/cookies.cljs
another option is to use http://goog.net.cookies directly like this (.get <http://goog.net|goog.net>.cookies "auth")
