Basically I have 2 questions regarding grails filters.

1. According to grails documentation you can do something like below in a filter

if (userId != paramsUserId) {
    flash.message = "You can only modify yourself"
    redirect(action: 'list')
    return false
}

If the above condition is true then how will the return statement get executed ?

1. Can I have a redirect in my filter to a some action which also has a redirect ?
