I have a drop-down list for locale selection, when the user changes it, then I send an ajax request to the action, where I set the session perimeter
Now the problem is that I have to return from the execute () method of the action
You can return HTTP 200 OK, which should be a blank, successful response.
<result name="empty" type="httpheader"> <param name="status">200</param> </result>
I would make a global result so that you can use it for any action.
