#region IHttpHandler 成员
bool IHttpHandler.IsReusable
{
get { return true; }
}
void IHttpHandler.ProcessRequest(HttpContext context)
{
string FileName = context.Server.MapPath(context.Request.FilePath);
if (context.Request.UrlReferrer.Host == null)
{
context.Response.ContentType = "image/JPEG";
context.Response.WriteFile("/no.jpg");
}
else
{
if (context.Request.UrlReferrer.Host.IndexOf("mydomain.com") > 0)
{
context.Response.ContentType = "image/JPEG";
context.Response.WriteFile(FileName);
}
else
{
context.Response.ContentType = "image/JPEG";
context.Response.WriteFile("no/jpg");
}
