Sorry for my bad presentation. Perhaps my english isn't really good.
My local web site is on my PC. I don't know if it possible to have a web server and a web client in the same time on Arduino.
The RST answer of my web site is at the end of the exchange between ethernet shield and my web server. And it interrupts the connection.
