Question

I am trying to create a cookie using Grails 2 (RC3). I am using this for a Facebook canvas app, which means that on every browser refresh, the session is lost.

I have tried using the cookies plugin, but it seems that it’s not compatible with Grails 2.

Any help would be GREATLY appreciated!

Answer 1

You can retrieve the value of a cookie in a GSP using the <g:cookie> tag

Hello  <g:cookie name="myCookie" />

You can also use this tag from a controller:

String name = g.cookie(name: 'myCookie')

You can set a cookie using the Servlet API

Cookie cookie = new Cookie("myCookie","Cookie Monster")
cookie.maxAge = 100
response.addCookie(cookie)
