public void ProcessRequest (HttpContext context)
{
context.Response.ContentType = "text/plain";
if (context.Request.Files.Count == 0)
{
context.Response.Write("No files uploaded.");
return;
}
int id;
if (String.IsNullOrEmpty(context.Request.QueryString["itemId"]) || !Int32.TryParse(context.Request.QueryString["itemId"], out id))

if (item == null)
