Problem redirecting from .aspx to .asp within IFrame

Hi,

I am using IFrame in my website. This IFrame holds pages based on menu.

I am redirecting several pages easily in IFrame.

Well, In one web form I have to call a .asp page, .asp page just process some data and further
redirects  to an external web site.

Problem is that when i am redirecting (within IFrame) to .asp
page - no action is performed. page postbacks and remains as
is.

There is nothing in ErrorLog. 

Any suggestions. Thanks!
