Modifying data in a ColdFusion application
The FMS event gateway lets ColdFusion applications modify Flash Media Server shared objects. The following steps
occur when data that affects a shared object is modified in a ColdFusion application:
The user submits a form that contains data to modify using a ColdFusion page.
1
2
The ColdFusion page calls the appropriate CFC, which contains a method to update the database.
The method in the CFC updates the database and calls a method in the FMS Gateway Helper.
3
The FMS Gateway Helper calls the FMS event gateway to update the appropriate shared object.
4
5
Flash Media Server updates the shared object.
Flash Media Server notifies the Flash client that a shared object has changed.
6
The Flash client makes the changes in its content as appropriate.
