When end-users access OOTB InfoCente webapp (or iConnect infocenter) using browsers with cookies persistence disabled, there are many potential problems like below:
1) For OOTB infocenter webapp, the user submits content rating will not work.
2) The iConnect infocenter portlet/tab will not work properly.
3) The Analytics event tracking will not work properly and hence the resulted Analytics report statistics are wrong/misleading.
4) The worse scenario (see note below for detail technical explanation) is that if large enough of end-users (hundreds in short period of time say in minutes) accessing the OOTB InfoCente webapp (or iConnect infocenter) using browsers with cookies persistence disabled, it may crash/bring down the WLS (or Tomcat) server hosting the target infocenter webapp due to resource exhaustion.
Note: With InfoCenter webapp deployed on WLS(Tomcat) server, we can only have so many users sessions per instance, which is driven mostly by number of concurrent open sessions. So, if end-users have cookies persistence disabled in their browsers, each click that user makes creates a new InfoCenter session in WLS(Tomcat) server, storing all of their user information over and over again. As a result, 'orphaned' auto-generated sessions (from each end-users clicks) will be left-behind at the WLS(Tomcat) server waiting for the session idle timeout (default to be 30min?) to expired before the resources can be reclaimed/reused.
