BackendFilesystem() Class Introduction
This class implements the auth.Sessions.Backend virtual base class, extending it to store the session information in the file-system. See the documentation for auth.Sessions.Backend() for more information on the methods and other details of it's use.
The one difference is how it's instantiated. The instantiation of the class takes the name of a directory that session information will be stored in. If this directory does not exist, it will be created. Note that if being used with mod_python/Apache integration, this directory will have to be set mode=read/write/scan by the Apache user. If you rely on the directory to get created, the parent directory will have to be read/write/scan by the Apache user, at least during the first instantiation of the class.
Example
See the "auth.Sessions.Backend()" page, which includes an example of using the "BackendFilesystem()" class.
Also, in the source code see "examples/test009/testbe-fs", which is an extensive test suite for the "BackendFilesystem()" class.
