Feature and Technical Overview | BlackBerry Enterprise Server process flows |
Process flow: Requesting BlackBerry Browser content while access control is turned on for the BlackBerry MDS Connection Service
1.A user requests Internet or intranet content from your organization's content server using the BlackBerry Browser on a BlackBerry device.
2.The BlackBerry device sends the request to the BlackBerry Enterprise Server over port 3101.
3.The BlackBerry Dispatcher sends the request to the BlackBerry MDS Connection Service over port 3200.
4.The BlackBerry MDS Connection Service checks the BlackBerry Configuration Database to verify whether pull authorization is turned on, and whether the user has permission to pull content from the specified content server.
If the user does not have permission to pull content from the specified content server, the BlackBerry MDS Connection Service rejects the request and sends an error message to the BlackBerry device.
5.The BlackBerry MDS Connection Service creates an HTTP session for the user and sends the user’s authentication credentials to the content server. If the user authenticates, the BlackBerry MDS Connection Service sends the HTTP request to the content server. If the user does not authenticate, the BlackBerry Browser displays an HTTP 403 Error message, and prompts the user to type the correct credentials.
6.The BlackBerry MDS Connection Service retrieves the content from the content server, converts it so that the user can view it on the BlackBerry device, and sends the content to the BlackBerry Dispatcher over port 3200.
7.The BlackBerry Dispatcher compresses the content, encrypts it using the device transport key of the BlackBerry device, and sends the encrypted content to the BlackBerry Router.
8.The BlackBerry Router sends the encrypted content to the wireless network over port 3101.
