Sorry for my english, it's not my native language

Hi !

I have a Wifly RN 171 on a shield (like this : https://goo.gl/yHkADu )
I want to load a HTML page from Arduino to my VPS to take information but i don't know how to do that.
How load page web page with Wifly RN 171 ?

My library : GitHub - Seeed-Studio/WiFi_Shield: WiFi library using WiFly
