404 page in TeamSite environment

ninickname

Hi guys :-)

I would like to insert a 404 error page for a website unter TeamSite 5.5.2 SP2 W2K. Reconfiguring the IIS is not the problem, but when a page is not found, iw(proxy?) already sends out header information so following (php) page can not be rendered any more:

Date: Thu, 17 Jun 2004 10:06:31 GMT
Server: Microsoft-IIS/5.0
Content-Length: 119
Content-Type: application/octet-stream
Set-Cookie: IWAUTH=52616e646f6d495[....]6e2ea7b9b9; path=/; expires=Fri, 01-Jan-2038 01:01:01 GMT
Set-Cookie: IWPROXY_PATHTRACK=/iw-mount/default/main/blablablablabla; path=/
x-teamsite-url-rewrite: true
X-Cache: MISS from xyz
Keep-Alive: timeout=15, max=100
Connection: Keep-Alive

Does anyone know where and how I can turn this off?
Thanks a lot in advance for any hin.
