General Information

The web_rest function is an action function that submits a REST request.

web_rest is not recorded. You can add it manually to a script.

The HTTP header can be modified to pass additional information about the request to the server. Using HTTP headers you can, for example, allow other content types in the response such as compressed files, or you can request a Web page only on certain conditions.

The method can be any method supported by the HTTP protocol. For example:

GET - retrieves a specific Resource from the Server.
POST - creates a new resource on the server.
PUT- updates the resource on the server.
DELETE - removes the resource from the server.
HEAD -retrieves the meta-data of the resource.
OPTIONS - retrieves information about actions that are supported for the resource.
