Ok, i got it. I suspected that I needed to pretend somehow I was "a real browser", so I looked for ways to do this. Man, it was difficult, but finally got it working. Here is one example of the code I came up with. I have another version in JAVA. Hah, I'm learning a lot. :)
import processing.net.*;
String data;
Client c;
String hostvar;
String getReq;
void setup() {
hostvar = "t.co";
getReq = "/L9n4hVDGbp";
c = new Client(this, hostvar, 80); // Connect to server on port 80
//c.write("GET / HTTP/1.1\r\n"); // Use the HTTP "GET" command to ask for a Web page
c.write("GET "+ getReq + " HTTP/1.1\r\n");
c.write("Host:" + hostvar + "\r\n"); // Host to which we are directing
c.write("User-Agent: Opera/9.80 (Windows NT 6.1; WOW64) Presto/2.12.388 Version/12.12; en-US; rv:1.9.0.7) Gecko/2009021906 Firefox/3.0.7\n"); //this does the magic
c.write("\r\n");
}
void draw() {
if (c.available() > 0) { // If there's incoming data from the client...
data = c.readString(); // ...then grab it and print it
println(data);
}
}
