Hi everyone,

I'm trying to retrieve all email address for the contact book in order
to invite people on my website.

I'm using ASP.NET 2.0, the .NET framework 2.0 and C#
When i'm trying to retrieve the XML, i got an error 403...

Actually i'm just using these code:

Authentication auth = Session["Auth" ] as Authentication;
if (Request.QueryStrin g["token" ] != null &&
Request.QueryString ["token"] .Length > 0)
{
if (auth.IsValidSigned Url(Request. Url) == true)
{
auth.Token = Request.QueryString ["token"] ;
auth.UpdateCredenti als();
Response.Write( "ok");
}
else
{
Response.Write( "error");
}
}

if (auth.IsCredentiale d == true)
{
string url =
"http://address. yahooapis. com/v1/searchCon tacts?format= xml&fields= name,email";
url += "&appid=" + auth.ApplicationId;
url += "&wssid=" + auth.WssId;

Uri address = new Uri(url);

XmlDocument doc =
auth.GetAuthenticat edServiceXmlDocu ment(address) ;

}
else
{
Response.Write( "Not authenticated" );
}

Please, help me to do this because i don't know why i don't have acces.
