What do you mean by "new module" ? is it "new module" or "new .ascx" ?

For example:

Module1
Control: View1.ascx
Control: View2.ascx

Module2
Control: View1.ascx
Control: View2.ascx

Do you want to redirect in Module1 from View1.ascx into View2.ascx in the same Module1 ? Or do you want to redirect from Module1-->View1.ascx into Module2-->View1.ascx ?

If you want to navigate from View1.ascx into View2.ascx in the same module, then you can use NavigateUrl() as usuall. or see Michael Washington tutorial about navigating between user control. The drawback is that your other module will dissapear. If you don't want to dissapear then, you have to create custom code like what Ventrian module did. If you have it, then you can see how it works.

HTH.
