By default the same session id is used once a session is established.
Regenerating a new Session Id on each request is controlled through a directive in the HTTP server configuration file (/www/instanceName/conf/httpd.conf). Adding the below value of PUI_SSN_REGENERATE
1 will create a new session id on each request and returned.
# Generate a new session id on every request. SetEnv PUI_SSN_REGENERATE 1
If PUI_SSN_REGENERATE
isn’t set or PUI_SSN_REGENERATE
is set to a different value than 1, then the same session id will be returned on a session is established.
