问题 How can i call a requestAction method from my view , to specific controller , which returns me results on basis of conditions i mention?

问题 I was googling on Sessions and mvc3, and I found this link.

This works fine, until you need to start using nested controllers. Example: There's a 'users' controller which holds methods like createUser(), editUser(), deleteUser() etc. All
