ASP+ enables clients to invoke web services using standard HTTP-POST requests, where the webmethod name is identified using the PATHINFO of the request (identical to the HTTP-GET model), and the method arguments are provided using name/value pair values UUEncoded within the body of the post (identical format to that used by standard HTML <form method=POST> tags).
Like the HTTP-GET invocation mechanism, requests sent via HTTP-POST in the current release are limited to supporting only standard datatypes and value classes and arrays of standard datatypes and value classes. Datasets and structs are not supported.
Like the HTTP-GET invocation mechanism, requests sent via HTTP-POST supports any NGWS runtime type as a return value.
