QUESTION:
How do I make my Arduino and Ethernet Shield accomplish the same task that I can so easily do from a web browser on my computer?
That is how do I request to go to a new URL once I am connected to a server. My real goal is to cause a sensed input on the Arduino to generate an email alert.
Followup question:
Am I limited to "GET" URLs only on the server specified at the beginning of my Arduino sketch? That seems to be the situation.
It probably depends on the PHP script on the server. The GET method can only send a limited length string of info with some character limitations. The POST method can send a large amount of data. If your PHP script on the server is written to handle POST request, then the POST method should work (depending on any limitations on what you are allowed to do on the server). It would be helpful to me and probably many others if you posted your working arduino code for future reference. Down the road I want to do something similar to have the arduino send text messages to my cell phone.
