namespace Web
{
class Program
{
static void Main(string[] args)
{
string RateHTML = "";
string tempHTML = "";

for (int i = 0; i < 10; )
{

try
{
// Download the data to a buffer.
WebClient client = new WebClient();

Byte[] RateHP =
client.Download Data("http://www.livescore.c om/default.dll?pag e=home");
RateHTML = Encoding.ASCII. GetString(RateH P);

// Download the data to a file.
client.Download File("http://www.livescore.c om/default.dll?pag e=home",

}

DateTime TimeNow = DateTime.Now;
if (tempHTML != RateHTML)
{
Console.WriteLi ne("Score change {0,1}:{1,2}{2,5 }",
TimeNow.Minute % 10, TimeNow.Second, TimeNow.Millise cond);
tempHTML = RateHTML;
}

Hi Macneed,
if the remote page is dynamic you cannot get header "Last-Modified".
The unique way I'm finding now is to parse the page and find a specific
section to check if has changed (in contents or length).
I'm not sure it's a legal way..
