If parameter <code>postData</code> is a blank string, then the GET request method is used, otherwise the POST request method is used.

|callback3Syntax = ArrayBuffer/String receivedData
|arg1 = string url The URL to send the HTTP request to.
|callback3Text = This callback function can potentially be called multiple times for the same request.
|arg2 = string postData The data to send as the body of the HTTP request.
|callback3Parameter1 = ArrayBuffer/String receivedData The data received, which could be all of the data or just 1 byte.<br>ArrayBuffer is used in JavaScript, String is used in other scripting languages.

|callback4Syntax = int curlErrorCode, int httpResponseCode
|arg4 = function completedCallback The scripting function to call when data has been entirely read on the connection.
|callback4Parameter1 = int curlErrorCode The CURL error code. 0 means success. [https://curl.haxx.se/libcurl/c/libcurl-errors.html CURL Error Codes]

|note = You can use this function to convert a JavaScript ArrayBuffer to a JavaScript String:
{{CodeSyntax|function ab2str(buf) {

|compat1 = In server version 1.1.22 and before, there was an issue where the connection would close after the '''dataReceivedCallback''' callback was called first time and did not return the received data length.

|compat3 = In previous server versions, for the JavaScript scripting language, the '''dataReceivedCallback''' callback was invoked with a string parameter instead of an ArrayBuffer parameter.
