This request function is implemented by the Java class com.arbortext.e3.FunctionAcl. It allocates an Arbortext PE sub-process and invokes an Arbortext PE Application written in ACL. It returns whatever HTTP response the Arbortext PE Application 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 Arbortext PE Application. The Arbortext PE Application uses routines closely modeled on those available to Java, JavaScript, and VBScript Arbortext PE Applications in retrieving request information and constructing the response. The request is structured like the following (without the line breaks):
