It might also be worth mentioning that inline will try to open Office Documents (xls, doc etc) directly from the server, which might lead to a User Credentials Prompt.

somebody tried to deliver an Excel Report from SSRS via ASP.Net -> the user always got prompted to enter the credentials. After clicking cancel on the prompt it would be opened anyway...

If the Content Disposition is marked as Attachment it will automatically be saved to the temp folder after clicking open and then opened in Excel from the local copy.
