You are right, it is possible to have pages outside of Sitefinity
, but such a page can be requested only if a page with the same link does not exist in the Sitefinity database. Currently you cannot change this behavior.
As for your second question:
Unfortunately, you cannot ignore the parent application configuration. It is normal to get such errors in the web.config, because some of the configuration elements are new in .NET 2.0 and were not supported in 1.1, so the sub-application cannot recognize them.
The only tips we can currently give you are:
- convert the shopping cart application from 1.1 to 2.0 or find a .NET 2.0 version
- move the shopping cart out of the Sitefinity web site
In the future we will provide a shopping cart module with Sitefinity.
Sorry for not being able to help you any further.
