Use Requests to send data to webpage - how?

[TheDGuy via Digitalmars-d-learn]

Hi,
i was sucessfull in installing requests and getting data from a 
webpage like this:

Request rq = Request();
Response rs = rq.exec!"GET"("http://somewebpage.org/SQL.php", 
["action":"getTemp"]);

But i am not able to send data to the webpage like this:

Request rq = Request();
Response rs = rq.exec!"GET"("http://somewebpage.org", 
[parameter:data]);

If i just type this:

http://somewebpage.org/?parameter=data

in my browser the webpage reacts as intended but with the 
Requests "GET" nothing happens. Do you know what i do wrong?
