HTTPMultipartdownloader is designed to download a very large single file
in several parts using multiple connections to the web server, and
assumes you have a lot of bandwidth.
The normal THttpCli component is fine for most downloading, but don't
drop them on the form, instead create them in code as a array and assign
all the properties and events in code, using the same events for all
instances of the component (this is what HTTPMultipartdownloader does
itself).
var
MyHTTPCli: array [0..9] of THttpCli;
procedure onHttpDataEvent (Sender : TObject; Buffer : Pointer; Len :
Integer);
procedure onHttpCommand (Sender: TObject; var S: String) ;
procedure onHttpHeaderData (Sender : TObject);
procedure onHttpSessionConnected (Sender : TObject);
for I := 0 to 9 do begin
MyHTTPCli [I] := THTTPCli.Create (Self) ;
with MyHTTPCli [I] do begin
Tag := I ; // so we can identify each instance
OnDocData := onHttpDataEvent ;
OnCommand := onHttpCommand ;
OnHeaderData := onHttpHeaderData ;
OnSessionConnected := onHttpSessionConnected ;
etc, etc,
end ;
end ;
