I have a Site with name eccommerce and then there are two different sub items with name Home and Buisness.
Now what I want is to show different 404 error page for both of them.
How can I achieve this?
One solution is build a 404 pipeline Processor in the httpRequestBegin pipeline. In this pipeline you found all kind of resolvers, like check if it is a Sitecore item, or File of url aliase. Afer the ItemResolver of this pipeline you can add a 404 Processor with your logic. For an example see: blog.martinmiles.net/.../handling-404-in-helix or www.sitecorlicious.com/.../
