Internet Pack | RemObjects Software

Built on TCP/IP

Internet Pack includes components for standard protocols such as HTTP, FTP, SMTP, and POP3. Its reusable connection classes also let you implement your own TCP/IP protocols.

The library is available for all Elements target platforms and can be used alongside Elements RTL in cross-platform projects.

Serve a File over HTTP

Create an Elements console project for any target and add a reference to RemObjects.InternetPack. Put an index.html file inside a www folder in the program’s working directory.

Fetch the File from a Client

With the server running, use this snippet inside another console project with the same references and the RemObjects.InternetPack.Http namespace in scope.

var lClient := new HttpClient;
writeLn(lClient.Get("http://127.0.0.1:8080/index.html"));

using _client = new HttpClient() {
  writeLn(_client.Get("http://127.0.0.1:8080/index.html"));

var client = new HttpClient();
writeLn(client.Get("http://127.0.0.1:8080/index.html"));

HttpClient client = new HttpClient();
writeLn(client.Get("http://127.0.0.1:8080/index.html"));

client := RemObjects.InternetPack.Http.HttpClient{}
writeLn(client.Get("http://127.0.0.1:8080/index.html"))

The Engine Behind ESP (and This Website)

Internet Pack supplies the networking layer for the built-in web server used by Elements Server Pages. You can also use it directly for your own clients and servers.
