As mentioned in one of my previous post if not setup correctly clustered environment can be a nightmare. Below are some of the configurations worth noting beforehand:
Server Affinity: a lost session
An HTTP (s) session should always be served by only one SAP Hybris application server otherwise session will be lost and user would need to re-login, even worse anonymous user will lose his cart and all other settings. To avoid this embarrassing experience, enable Sticky Session at application load balancing layer which will stick one session to one SAP hybris server.
Very often redirect rules are defined at load balancing layer to redirect complete URL (base + context )-e.g. http://doodle.com/fun to base URL e.g. http://doodle.com.
Here one exception should be medias because their urls are appended with /medias at end of base URL and redirecting these URLs to base URL wont load medias:
eg. a call to medias URL – e.g. http://doodle.com/medias/abc/456789.jpg will be replace with http://doodle.com which will fail loading of medias into SAP Hybris applications.
