Non-sticky session manager for Apache Tomcat 7.xx with Redis and disk store implementations.

Build

Compile using maven

mvn compile package

Install

Copy tomcat-redis-session-manager-{version}.jar to TOMCAT_BASE/lib directory.

Redis store

Configure Tomcat by adding the following block to context.xml (or context block of server.xml)

<!-- RedisSessionManager 
     Single host config attributes:
        host - defaults to localhost
        port - defaults to 6379
    Sentinels config attributes:
        sentinelMaster - master name
        sentinels - comma separated list of [sentinel-host:port]
    Config attributes:
        database - Redis DB to use (defaults to 0)
        timeout  - Redis connection and so timeout (in milliseconds, defaults to 2000)
        password - Redis auth password
        connectionAttempts - Number of attempts to connect to redis (defaults to 20).
        connectionAttemptDelay - Delay between attempts (in milliseconds, defaults to 500). NB: Make sure that total duration of connectionAttempts*attemptDelay is enough for new master to be chosen. 
        operationAttempts - Number of attempts to retry redis operation if it fails.  (defaults to 3)
        maxInactiveInterval - The default maximum inactive interval for Sessions. Is overridden by web.xml session-timeout setting (in seconds defaults to 1800) 
        sessionIdLength - The session id length of Sessions. (defaults to 16)
        keepSessionDuration - Cached sessions will be reused for specified duration after being cached. Will greatly speed up concurrent requests to the same session, but at a price of possible desync if used in cluster environment with dynamic load balancing (defaults to 10)
        cacheClearupDelay - Delay between executions of session cache clearup task, in seconds. (defaults to 60)
    Jedis pool config attributes (optional):
        poolXXX - where XXX are properties from GenericObjectPoolConfig see (https://commons.apache.org/proper/commons-pool/apidocs/org/apache/commons/pool2/impl/GenericObjectPoolConfig.html)
