The commerce feature works in conjunction with the authentication feature.
It consists of an additional database which stores permissions to individual
clips. To authenticate visitors, the RealServer stores user IDs and
passwords or client IDs, and their associated access permission information.
When a client tries to access a clip, the RealServer looks up this information
to see whether the client or visitor is authorized to view the clip. The
information can be stored in either a series of text files or in a database.
Templates for common databases are installed during installation.
Two methods are supplied with RealServer: text file and database. The text file storage method uses a combination of directory structure and text files to achieve a sensible data storage method. It is the default method. The database templates included with RealServer use a similar structure to the text file method, in a more familiar database format. |
