Restricting user access to media content in the BlackBerry Browser

You can use standard definitions for MIME media types so that you can restrict the media types that the BlackBerry® MDS Connection Service can send to the BlackBerry® Browser and other applications on BlackBerry devices.

  2. Click BlackBerry MDS Connection Service.

Configure download limits for media content types

You can configure the BlackBerry® MDS Connection Service instances in your organization's environment to limit the size of media content that BlackBerry device users can download to BlackBerry devices during each connection. Each request for data that the device makes to the BlackBerry MDS Connection Service is a connection. If you do not configure a limit for media content types, the default values apply.
