Routing error with popup

I am getting a routing error when trying to open a window with :popup
=> true

I do not get the error on localhost only on the server.

I am only getting a routing error when accessing .../ICA/...

Code

This is what my dev logs have to say. I noticed that my paremeters are
not being set - which then makes since why I am getting the error, but
why are my parameters not getting set?

Thanks to the people on this list, I fixed it.

The problem was that I called it ICA - changed it to Ica and it works.
I guess unix/linux is more case sensitive then window so when I
deployed to a unix box it broke the ICA call.

Thanks.
