New HTTP Client API

The RTL provides several new network units with members that let you create an HTTP client, send requests to HTTP servers and handle their responses.

Using an HTTP Client explains how to use the two new HTTP components, TNetHTTPClient and TNetHTTPRequest, to handle HTTP requests. See also the main HTTP client classes:

THTTPClient, that represents an HTTP client.

THTTPRequest, that represents a request from your client to a server.

THTTPResponse, that represents the server response to a request from your client.
