MultiDomain doesn't handle form

[eduardocereto]

We should be able to handle forms for multidomain.

I know that for POST forms we can use _linkByPost.

I need to refresh my memory on what is the best way to track GET forms to setup cross domain. Anyone able to help me here?

Turns out there is no good way to track GET forms that can be done automatically. There are some ways to do it but you need to be aware of several caveats on a case by case basis. So GET forms are out. POST forms still a feature I want.
