We have a multisite SiteCore setup with 2 sites within the same .Net solution.
This works by setting the rootPath property on a Site Definition in web.config to limit the site to part of the SiteCore folder structure.
This works well apart from when pages are created with the same name as in the other site then it's serving content from the other site! We have inherited a fair bit of custom code in this solution form the other site so this may be the cause but dont know what Im looking for ...
Thanks
