This request function is implemented by the Java class com.arbortext.e3.FunctionAcl. It allocates an Sous-processus Arbortext PE and invokes an Application Arbortext PE written in ACL. It returns whatever HTTP response the Application Arbortext PE generates. The ACL function must be configured in the Allowed Function List (see The Allowed Functions List) in e3config.xml or the Arbortext PE Request Manager will return an error message.

The entire HTTP request, including the request line, headers, query parameters, and request body are made available to the ACL Application Arbortext PE.

The request is structured like the following (without the line breaks):
