Solution to the problem of session conflict caused by Weblogic multi-application deployment in one domain
Recently , multiple applications have been deployed under a domain of Weblogic at the same time, and there has been a problem of session conflict. The phenomenon is like this, access A is normal, but after jumping from application A to application B , the session of application A is invalid immediately. Because I have encountered a similar situation on tomcat before , I immediately thought that it should be the problem of session conflict. Every application will write a cookie named jsessionid when writing a cookie that saves session information . The effect achieved in this way is that when application A is accessed first, application A writes a cookie named jsessionid to save its session id . As a result, application B saves its session id through jsessionid when accessing application B.The id of the session , thus overwriting the sessionid of the A application , and the session of the A application will be lost the next time the A application is accessed .
The solution is to create a new weblogic.xml file in the WEB-INF directory of the application, and specify the cookie name for saving session information through the CookieName of the session-param of its session-descriptor to ensure that the CookieName between each application is unique.
