Enter 1 to enable IIS identity impersonation. Leave empty to disable identity impersonation. If identity impersonation is disabled, then the Gateway Caching Server runs under the Network Service account. If this property is not included, the default value of 1 is used and IIS identity impersonation is enabled.
For example: IIS_ASPNET_IMPERSONATION=""
Note:
Ensure the account the Gateway Caching Server is running under has modify rights to the installation and cache directories. If modify rights are not granted, you may encounter permissions errors in modules attempting to modify files on the server.
This setting is required.
