Class
org.exist.xquery.functions.session.SessionModule
The HTTP session is a piece of memory that is allocated by the Java
application server underlying eXist and associated with a series of
requests from a single client. So that the Java application server can
identify each request from a client as belonging to the same ses‐
sion, a unique identifier is generated and given to the client. This is
expected to be sent back to the server on each request. This identi‐
fier may take the form of an HTTP cookie or a parameter in the
HTTP URL query string; either way, it will be named JSESSIONID .
A session can contain data that is kept alive between requests. Access to a session is
provided through this module. It is described in “The session Extension Module” on
page 211 .
