New Post: Multi site and incorrect redirection

Allright, thank you for explaining.

That is indeed possible, but will require some custom code

1. Write a HttpModule that listens to all incoming requests
2. Check if the request maps to a C1 page
3. Check if the resolved page belongs to the site mapped to the hostname for the request
4. If not, set the HttpStatusCode to 404 and end the request
   

I can post the code here tomorrow if you don't know how to get started on writing the required code, i suppose its about 30 lines.
