Since all CAE and Studio instances must authenticate against HCL Commerce Server for protected REST requests, and by default all instances use the same technical user name, it is required to configure your HCL Commerce Server to allow multiple logins per user at the same time using the AllowMultipleLogonForSameUser property.

Otherwise, multiple clients (CAE and Studio, for instance) will terminate each others session and need to login again frequently, causing long delays on the REST communication layer.

Please refer to HCL Knowledge Center for details on how to set the AllowMultipleLogonForSameUser property.
