Sorry for double posting.
After some minutes online with the server, it stops working, like after 5 minutes or so.
Here's the code, it's pretty simple, its a variant from a Example Sketch of the book: Arduino Cookbook.

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
byte ip[] = { 192,168,100,110 };
byte gateway[] ={ 192, 168, 100, 1 }; // add this if needed by your router or gateway
char buffer[8]; // buffer holding the requested page name
Server server(8000);
void setup()
{
Serial.begin(9600);
Ethernet.begin(mac, ip, gateway);
server.begin();
delay(250);
Serial.println("Ready");
}
void loop()
{
Client client = server.available();
if (client) {
TextFinder finder(client );
int type = 0;
while (client.connected()) {
if (client.available()) {
// GET, POST, or HEAD
if(finder.getString("","/", buffer,sizeof(buffer))){
if(strcmp(buffer,"POST ") == 0){
finder.find("\n\r"); // skip to the body
// find string starting with "pin", stop on first blank line
// the POST parameters expected in the form pinDx=Y
// where x is the pin number and Y is 0 for LOW and 1 for HIGH
while(finder.findUntil("pinD", "\n\r")){
int pin = finder.getValue(); // the pin number
pinMode(pin, OUTPUT);
digitalWrite(pin, HIGH);
delay(250);
digitalWrite(pin, LOW);
delay(250);
}
}
sendHeader(client,"Post example");
//create HTML button to turn on pin 8
client.print("<form action='/' method='POST'><p><input type='hidden' name='pinD8'");
client.print(" value='1'><input type='submit' value='On'/></form>");
//create HTML button to turn on pin 9
client.print("<form action='/' method='POST'><p><input type='hidden' name='pinD9'");
client.print(" value='1'><input type='submit' value='On'/></form>");
client.println("</body></html>");
client.stop();
}
break;
}
}
// give the web browser time to receive the data
delay(1);
client.stop();
}
}
void sendHeader(Client client, char *title)
{
// send a standard http response header
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println();
client.print("<html><head><title>");
client.print(title);
client.println("</title><body>");
}
The Ethernet Shield IC also gets incredibly hot. Any ideas?
