How to get the same session on subdomains in grails

I have one application that processes multiple subdomains, such as

  • sub1.domain.com
  • sub2.domain.com
  • www.domain.com
  • domain.com

The user can switch between these subdomains when using the application. When this happens, the session is not split between these subdomains. I use tomcat as a server for development and production.

I try to create shared sessions in development first. Upon reading, it turned out that the way to achieve this in tomcat is:

<Context sessionCookiePath="/" sessionCookieDomain=".domain.com">

Is there a way to install this on tomcat in a development environment?

I tried the code below in _Events.groovy, without success:

eventConfigureTomcat = {tomcat ->
    def context = tomcat.addContext("","/")
    context.setSessionCookieDomain(".domain.com")
    context.setSessionCookiePath("/")
}

I get java.lang.IllegalArgumentException: addChild: child name 'error is not unique

, ( , getContext):

eventConfigureTomcat = {tomcat ->
    def context = tomcat.getContext("") //This function does not exist
    context.setSessionCookieDomain(".domain.com")
    context.setSessionCookiePath("/")
}
