Multiple deployment with jgroup request re-login

#1

I follow the document to configure Interaction sharing user session between two same app in different docker container, for implementation that user can use the app in two URL in one time log-in.
here are two buildWar config for app and app2:
app

task buildWar(type: CubaWarBuilding) {
    includeJdbcDriver = true
    includeContextXml = true
     appProperties = ['cuba.automaticDatabaseUpdate': true,
                     'cuba.cluster.enabled': true,
                     'cuba.webHostName': 'app',
                     'cuba.webPort': '8080',
                     'cuba.dataSourceProvider'     : 'jndi']

app2

task buildWar(type: CubaWarBuilding) {
    includeJdbcDriver = true
    includeContextXml = true
     appProperties = ['cuba.automaticDatabaseUpdate': true,
                     'cuba.cluster.enabled': true,
                     'cuba.webHostName': 'app2',
                     'cuba.webPort': '8080',
                     'cuba.dataSourceProvider'     : 'jndi']

app docker port map 8888:8080
app2 docker port map 9999:8080
they use the same jgroups.xml file copying from cuba-core module without any modification
the log comes from app:

bui after I loggined in localhost:8888/app returning to another browser tab localhost:9999/app, the 9999 page shows session expired, need login again, when I loggined in 9999 then the 8888 serveer shows it is session expired

Hi,

My guess is that app server cookies are mixed up. There was a similar issue for the Vaadin framework. You can try to fix it by setting up a reverse proxy / balancer in front of the applications, it is a recommended way for clustering the app. There is a doc describing this. I guess you can add it to your docker compose configuration.

thx very much for your reply, I debugged the cookie using the Firefox debugger confirming that they mixed up the session cookies(same session name with different session value), I solved it by sending same cookie(same session name and same session value) to the server.
