GPRS access : wrong URL

Official Hardware Retired GSM Shield
1

Hi,

I cannot access some websites with my GSM shield, for example, the http://arduino.cc/latest.txt page.
It seems that the modem tries to get data from http://64.131.82.241/latest.txt which leads to a HTTP 404 error (64.131.82.241 is the IP address of the arduino.cc server).
It looks that this is a problem of the provider (Lycamobile). But with my cellphone (Nokia C2-00), I can access the page using the same GPRS parameters (APN, login, password).

What could I try ?

PS : I use the arduino sketch http://arduino.cc/en/Guide/ArduinoGSMShield?action=sourceblock&num=3

I solved the problem by adding a Host header to the request :

GET /latest.txt HTTP/1.1[CR][LF]
Host: arduino.cc[CR][LF]
[CR][LF]

This modifies the code into :

// Make a HTTP request:
client.print("GET ");
client.print(path);
client.println(" HTTP/1.1");
client.print("Host: ");
client.println(server);
client.println();
