Configuring Organize Space for Load Balancing
Some pages in Organize Space still exist as ASP.NET pages, operating under the ISHCM web application. If your implementation has a scaled-out Content Manager with the front-end is operating behind a load balancer, you may need to configure a machine key for all instances of the ISHCM web application to ensure the proper functioning of various security features including anti-forgery and other validations.
About this task
Under Network Load Balancing (NLB), all instances of the ISHCM must use the same machine key. You can use the Machine Key feature of IIS to generate a Validation key and Decryption key for one ISHCM instance and then copy them to other instances.
