Consider the following scenario:
For example, the CGI application sets multiple "Set-cookie" response headers. However, the client receives only the last cookie value.
In IIS 7.0, multiple value instances of the same response header are not appended. Instead, all instances are replaced by the last value only.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Windows Vista Service Pack 1.
This behavior can affect any CGI application that sets multiple instances of the same response header. One known example is Microsoft Virtual Server. If you host a Virtual Server Administration Web application on IIS 7.0, and you use the Virtual Server Administration Web application to change the Web site properties, the changes are not saved as expected. This occurs because personal settings of the Virtual Server Administration Web application are stored in the form of cookies. If the Virtual Server Administration Web application is hosted in IIS 7.0, and the application runs on a Windows Vista-based computer, only the last cookie that is set is saved.
Non-Microsoft CGI applications can also be affected. Microsoft has been notified that the Movable Type publishing platform application is affected by this problem.
