Since the normal Tomcat clustering is based on multicasts, it can not be used in Microsoft Azure. Is there another option? Thanks in advance for reading and answering my question. Every comment/idea is highly appreciated 回答1: One option would be to use memcached-session-manager: http://code.google.com/p/memcached-session-manager/ It's a tomcat session
