I send stream to user and everyhting works fine except f.Free; I get here Access Violation. f := TFileStream.Create(AProcessFileNameResult, fmOpenRead and fmShareDenyWrite); try Response.ContentStream := f; Response.CustomHeaders.Values['Content-Disposition'] := Format('attachment; filename=%s', [ExtractFileName(AProcessFileNameResult)]); Response.ContentType := GetMimeTypeFromFile(ExtractFileName(AProcessFileNameResult)); Response.SendResponse; Handled := True; finally f.Free; end; Back to top Dennis Passmore Guest Posted: Fri Feb 09, 2007 9:03 pm    Post subject: Re: EWebBrokerException Maximum number of concurrent connect Quote: Response.ContentStream := f; Response.SendResponse; Handled := True; finally f.Free; end; When you passed F to the Response object it then owns the stream and has already Free'd in SendResponse so do not try to free it since it no longer exists.
