Set Cookie httpOnly to false In Grails.

[Kamal raj]

I'm currently creating an application, in which I use code like this: 

session.user = user.username 
Hence I get JSESSIONID cookie created. But I want my client side program to read this cookie; But since its been set HttpOnly to true I can't get value from client side. 

How one should change the cookie Httponly to set false in grails? So that client side code can read them? 

Thanks.
