You can use the @LANGUAGE directive to set the language that will be used to interpret the commands in a script. You can set your scripting language to any scripting engine that has been installed in IIS. The default scripting language is VBScript, so if you do not include a @LANGUAGE directive in your script, the script will be interpreted by the VBScript engine.
<%@ LANGUAGE = scriptengine %>
You can change the default scripting language with the IIS Admin Objects AspScriptLanguage property. You can apply this property to a Web Service, Web Server, Virtual Directory or Web Directory. For more information, see Using IIS Admin Objects.
