Using in arduino code that is making a get request is strange. Below is some test code you can try substituting your url for the one for my web site. Note that if your site uses virtual hosting, you may also need to make accomidations for that.
//zoomkat 2-13-12
//DNS and DHCP-based web client test code
//for use with IDE 1.0
//open serial monitor and send an e to test
//and to see test result
//for use with W5100 based ethernet shields
//browser equivelant URL:
// http://web.comporium.net/~shb/arduino.txt
//note that the below bug fix may be required
// http://code.google.com/p/arduino/issues/detail?id=605
#include <SPI.h>
#include <Ethernet.h>
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; //physical mac address
char serverName[] = "web.comporium.net"; // zoomkat's test web page server
EthernetClient client;
