How to run a 'program' from a web browser?

I know how to send RF commands via web browser, but I do not know how to run a program from it. I assume it is possible with a command such as:

http://192.168.1.1/api/HomeAutomation.X10/RF/Control.RfSend/

Would someone please show me the format to run a program instead?

It’s all in the API documentation HomeGenie Documentation

Actually THIS ONE is documented there! I just assume it was not as most others are not there. I found it and made it work.

They’re all there. Any you’ll need anyway. That’s why I linked to that particular page of the API documentation.
