I've been tired of getting comments and trackback posts for DotText that are essentially spam.
Hence, using Borland Developer Studio 2006, I enhanced Dottext to return 404 to these requests.
In web.config, I updated the HttpHandler to read as follows:
<HttpHandler pattern="^(?:\/(\w|\s|\.)+\/services\/trackbacks/\d+\.aspx)$" type="Dottext.NoTrackback, Dottext.SpamBlocker" handlerType="Direct"/>
The corresponding class follows.
unit Dottext.SpamBlockerImpl;
interface
uses System.Web;
// Set default namespace to Dottext in Project options!
NoTrackback = class sealed(System.Object, IHttpHandler)
public
function get_IsReusable: Boolean;
procedure ProcessRequest(context: HttpContext);
end;
implementation
{ NoTrackback }
function NoTrackback.get_IsReusable: Boolean;
begin
Result := True;
end;
procedure NoTrackback.ProcessRequest(context: HttpContext);
begin
context.Response.StatusCode := 404;
context.Response.&End;
end;
end.
