(Plesk for Windows) Custom Handlers Policy
By default, IIS handlers defined in customers’ web.config files override those defined on the web server level. You can prohibit customers from overriding the handlers via the web.config files. Go to Tools & Settings > Security Policy and select Prohibit the ability to override handlers via web.config.
Please note the following:
- Choosing this option will increase the security but may impact the operation of some customer’s applications.
- This option will influence newly created domains only. The existing domains must be reconfigured for the new policy to take effect.
