Connect Arduino and phpMyadmin

The problem is that I own an account behind a virtual Linux server of someone else and that the code gives a bad request.
I think the problem occurs because of wrong setup of IPAddress server declaration. I need it to be declared as a domain.
char server ('www.domain.com'); doesn't work as well...

#include <SPI.h>
#include <Ethernet.h>

byte mac[] = {  0x00, 0x00, 0x1A, 0x2B, 0x3C, 0x4D };
IPAddress ip(192, 168, 1, XXX);
IPAddress gateway(192, 168, 1, 254);
IPAddress subnet(255, 255, 255, 0);

IPAddress server(XXX,XXX,XXX,XXX); // Change to your server ip

EthernetClient client;
int totalCount = 0;
int loopCount = 0;

void setup() {
  Serial.begin(9600);

  pinMode(4,OUTPUT);
  digitalWrite(4,HIGH);

  Ethernet.begin(mac, ip, gateway, gateway, subnet);
  delay(2000);
  Serial.println("Ready");
}

char pageAdd[32];
void loop()
{
  if(loopCount < 5)
  {
    delay(1000);
  }
  else
  {
    loopCount = 0;
    sprintf(pageAdd,"/arduino.php?temp1=%d",totalCount);
    if(!getPage(server,pageAdd)) Serial.print("Fail ");
    else Serial.print("Pass ");
    totalCount++;
    Serial.println(totalCount,DEC);
  }    

  loopCount++;
}

byte getPage(IPAddress ipBuf,char *page)
{
  int inChar;
  char outBuf[128];

  Serial.print("connecting...");

  if(client.connect(ipBuf,80))
  {
    Serial.println("connected");

  sprintf(outBuf,"GET %s HTTP/1.0\r\nHost: http://www.domain.com\r\n\r\n",page);   // Should it be http://www.domain.com/arduino.php\r\n\r\n"  ???
    client.write(outBuf);
  } 
  else
  {
    Serial.println("failed");
    return 0;
  }

  int connectLoop = 0;
  
  while(client.connected())
  {
    while(client.available())
    {
      inChar = client.read();
      Serial.write(inChar);
      connectLoop = 0;
    }

    delay(10);
    connectLoop++;
    if(connectLoop > 1000)
    {
      Serial.println();
      Serial.println("Timeout");
      client.stop();
    }
    
  }

  Serial.println();

  Serial.println("disconnecting.");
  client.stop();

  return 1;
