Anyone have any experience with this? I'm considering using it to call a page that would normally be called using Response.Redirect - however, I want control returned to the calling page. I also want to suppress and/or capture the output that the target page produces. Does anyone have any in-depth information on how this call works (or have a good link to a page that explains it)? Thx in advance. edit: Most of the pages I've found online just explain the basics of the call - I'm looking for something more detailed. Also, this isn't homework in case anyone's curious.
