Wiz550io - simple HTTP Request


i have the Wiz550io and connected to ATmega8.
I run a ready-to-use project from : GitHub - oltzen/W5500Example: W5500 with ATmega

All is up running fine.
SInce i am new to Ethernet, how can I send a simple http request? Means i want to call a specific website (fire and forget) , I dont want to receive any data, just call the page.

Is there a simple method?
