IIS application pool can work in three modes:
- Shared pool is always used for all clients and domains.
- Dedicated pool is always used for every client and domain.
- Shared pool is used for clients and domains by default; clients are allowed to assign dedicated pools for their customers.
To change the IIS application pool working mode:
1) Go to Server > IIS Application Pool.
2) Select Global Settings tab.
3) Select the required mode and click OK.
