ÉlevéeNiveau 1Automatiséeiis

Description

Handler mappings can be configured to give permissions to Read, Write, Script, or Execute depending on what the use is for - reading static content, uploading files, executing scripts, etc. It is recommended to grant a handler either Execute/Script or Write permissions, but not both. The server-level handlers accessPolicy must not contain Write together with Script or Execute. PowerShell 5.1 with the WebAdministration module; run elevated.
