SPItemEventReceiver and Redirect/Transfer (to other list items's f

[winnes]

Environment: SQL2005 and WSS3 on Windows Server 2008 (not 2003!)

WSS Customization as follows (simplified):
- 2 Custom Lists implicitly linked through passed through ID
- In SPItemEventReceived all data is synced into SQL (add-update-delete)

First List already has this:
- In SPItemEventReceiver redirect to EditForm for the just created ID (this
way a Gridview and New button appears in order to create linked items in 2nd
list)
(cf.
http://www.entwicklungsgedanken.de/2008/03/27/redirecting-from-newformaspx-to-dispformaspx-after-creating-a-new-item/)

On the last mentioned EditForm, new button links to 2nd list NewForm.
On submit (also for Edit... and Delete) this should redirect us to the
EditForm of the first list's item.

My guess was to di this in SPItemReceiver events as well, but apparently
neither SPUtility.Redirect, HttpContext.Response.Redirect nor
HttpContext.Server.Transfer do the trick (while they do in Windows Server
2003!?)

Any ideas are greatly appreciated.
