FTP Request Filtering Page

Applies To: Windows Server 2008 R2

Use the FTP Request Filtering feature page to define the request filtering settings for your FTP site. FTP request filtering is a security feature that allows Internet service providers (ISPs) and Application service providers to restrict protocol and content behavior. For example, using the File Name Extensions tab you can specify a list of file name extensions that are allowed or denied.
