Recently moved a Kentico 6 site to IIS7, and we're having a problem with extensionless urls using the suggested method here: http://devnet.kentico.com/docs/devguide/index.html?custom_url_extensions_iis7.htm

The problem we run into when setting up <modules runAllManagedModulesForAllRequests="true"> is not that the extensionless urls don't work, they do, all the aliases work as well, but when we set it to run this way, Kentico doesn't honor any folders that physically exist and any default document settings.

For example, we have some old classic ASP Code that is still running in a folder. If we setup the above, and link to:

http://www.site.com/ASPFolder or http://www.site.com/ASPFolder/, Kentico processes this, and doesn't give things a chance to see that there is actually an index.asp (which is setup as a default document) file in there that it should link to. Kentico can't find it in it's file structure and gives a 404. Things work fine if we link directly to http://www.site.com/ASPFolder/index.asp

Is there additional configuration that can/should be done to allow IIS7 to know there is a physical file to load before Kentico handles it, or will we have to change how we link to things?
