I'm looking into configuring wf 17 with distributed cache for sessions, but I have problems making it work properly. It's a distributed configuration, I use basic authentication and when we send the post to /j_security_check it's going to one node and the get for /index.html after the authentication is done successfully it's going to a different node. When the request arrives on the second node I have this exception :

2019-10-16 17:17:39,901 TRACE [org.wildfly.clustering.web.infinispan] (default task-9) Session _ttZ3PQsisp4qCdTlkY512jYoG02S3DiYgpDUGjJ not found

I can see on the other server where the /j_security_check post happened:

My configuration for inifinispan cache is:

                <cache-container name="web" default-cache="dist" module="org.wildfly.clustering.web.infinispan">
                    <transport lock-timeout="60000"/>
                    <distributed-cache name="dist" remote-timeout="17500" l1-lifespan="0" owners="2">
                        <locking acquire-timeout="60000" isolation="READ_COMMITTED"/>
                        <transaction locking="OPTIMISTIC" mode="BATCH"/>
                        <file-store/>
                    </distributed-cache>
                </cache-container>

As long as the session is cached in infinispan how come when the request hits the second server initially it's not found but when trying to create it complains that it already exists?

Also, I tried configuring the distributable-web:1.0 wf subsystem to use the above-mentioned cache but the output is the same. Not sure if that is needed, if I have the tag in the web.xml it's going to be the same "default" distributable-web subsystem right?

A different situation that I noticed and I don't understand:

This happened on the same node, I receive the response with the above session and moments after that it's not able to find the session, eventually receiving a 404 for j_security_check.

问题是重定向的请求在前一个请求完成提交之前试图读取会话。删除事务和锁定标签解决它。
