Summary :
When multiple J2EE Application Servers within the same domain are accessed via the same browser, overlapping JSESSIONID cookies may occur, leading to issues such as lost user sessions or Web Dispatcher failing to find a destination server. This typically happens because cookies aren't confined to a specific host, due to a non-specific 'Domain' attribute setting in the cookie configurations. To resolve this, SAP recommends configuring cookies at each J2EE Engine to either remove the domain attribute or adjust the Path attribute, especially when a proxy is involved or servers exist in subdomains. Detailed steps for implementing these changes in different versions of the J2EE Engine are provided.
