Grails URL mapping to always show www.mysite.com in browser address bar

I have grails application which has several controllers and actions. Suppose a user goes to:

http:// www.mysite.com/user/register

which means action register in controller user is executed. what I want is that when the response is r开发者_如何学编程eceived by the browser ( or when the request is made by the browser), the browser URL bar should display (the root path): http:// www.mysite.com

without executing the default action and controller (mapped to the root path '/' in the URLMappings.groovy).

Is this possible and how to do that?

You can either redirect to root controller+action:

redirect controller: "home", action: "index"

(though this will call the action, is it that you're trying to aviod?) or call

render template:'some_template', model: '[some: model]'

for root page. It will work if you extract root page elements to a template and have a simple model in it. We, for instance, have no model at all for a root page.

If you wish to always stay on root page, you'll have to use redirect: how can browser go from action page to root page without being told to? I believe you can use params property of redirect method, or flash variable, to tell the root action what to do and what not to do.
