Module dhm.sqlsession
Session storage class
When dealing with multiple simultaneous sessions as is common with
web-based programming it is very useful to store session information on
the server. To do this a special kind of database is needed which allows
for multiple readers and writers in parallel.
This module implements such a database using a SQL database. The
tables have to use this structure:
CREATE TABLE paidnet(
id VARCHAR(16) NOT NULL,
attribute VARCHAR(16) NOT NULL,
value VARCHAR(255) NOT NULL,
CONSTRAINT single_key UNIQUE (id, attribute));
