Ajax, JSON, and XML-RPC

Ajax, JSON, and XML-RPC are technologies typically used by client side code when communicating with a server.

Our Ajax package includes a collection of services for creating interactive web applications without having to reload the complete web page in response to each user input, thus making the interaction faster.

Ajax is a group of interrelated web development methods used on the client-side to create interactive web applications. The name implies that XML is used. However, many prefer to use URL-encoded data when sending data from the client to the server and JSON as the response. URL-encoded data sent by JavaScript code matches HTML form data sent by a browser when a user clicks the submit button. Managing form data received from a client is very easy when using LSP. The server also includes functions that automatically create JSON from Lua tables.

Ajax (Asynchronous JavaScript and XML)

AJAX and JSON are typically used by JavaScript code in modern web based user interfaces when querying the server in real time. JavaScript code may, for example, send URL-encoded data to the server, and the server may respond by sending back a JSON object.

JSON

The JSON format is often used for serializing and transmitting structured data over a network connection. It is often used to transmit data between a server and web application, serving as an alternative to XML.

Barracuda supports JSON-RPC, where data is sent as JSON from the client to the server and vice versa. JSON-RPC is a good alternative to the more complex SOAP protocol. We also provide a JavaScript JSON-RPC client library that can be used by the client web-application. However, for many applications, Ajax as described above is sufficient.

XML-RPC

The XML-RPC server stack provides a server API virtually identical to the JSON-RPC server API. XML-RPC is typically used when creating web-services for legacy client XML-RPC implementations.
