public class Handler : IHttpHandler {
public void ProcessRequest (HttpContext context) {
string strSql = "Select IP from Web where _D="+context.Request.QueryString["id"];
DataUtility objData = new DataUtility();
DataSet dstList = objData.QueryData(strSql);
context.Response.ContentType = "text/plain";
context.Response.Write("document.write(\"" + dstList.Tables[0].Rows[0][0].ToString() + "\")");
}
public bool IsReusable {
get {
return false;
}
}
