Chapter 6: Java Session Service (JSS) configuration 65
Session management with JSS
■
The first machine hosts the Apache web server,
■
the two other machines contain an instance of the Borland web container
as well as each hosting the JSS,
■
and the fourth machine hosts the relational database (JDataStore or a
JDBC datasource).
If an interruption occurs between the Apache web server (Machine 1) which is
passing a client request to the first web container instance (Machine 2), then
the second web container instance (Machine 3) can continue processing the
client request by retrieving the session information from the JSS (Machine 4).
The items in the Shopping Cart are retained and the client request continues
to be processed.
