This is one of the major milestone I have achieved recently to customize the report viewer web part for SharePoint sites. The issue I was facing: the SharePoint site which I have developed was too complex and it exposed via 3 zones. http://intranetsite, http://extranetsite, https://internetsite
http://intranetsite – which is Windows based authentication site and for intranet people.
http://extranetsite – Which is Windows based authentication site and for extranet people
http://internetsite – Which is Forms based authentication site and for internet people.
