In our windows application, we used crystal reports. If a customer needed a custom report, we could create it and then send them the rpt file. The customer would then simply add the report file to a custom folder, and could access it directly from our application.

Using a web app, how is this possible. It seems like anything created, using ssrs, crystal, or even telerik reporting must be embedded.

What are some methods for providing custom reports to users of an asp.net web application?
