We are using indy version 9.00.10.
I've tried to set these values(ex):

Host := any web adress.
Port := 80
ProxyParams.ProxyServer:= proxyserver.
ProxyParams.ProxyPort := 8080
with and without BasicAuthentication, ProxyUserName and Proxypassword.

And if I try to call get(Url) - methode, it fails, it only resolving the
proxyserver and telling me that the page cannot be viewed. If I try the
connect methode it resolves the proxy server and the webadress.
Is there anyone that can telling me how to use indy components with
proxy,any examples?

I have had the same problem and I figured out that the password and username
can be set in the
following event:

procedure TfrmInternet.HTTPProxyAuthorization(Sender: TObject;
  Authentication: TIdAuthentication; var Handled: Boolean);
begin
  if frmProxyUser.ShowModal = mrOK then begin
    Authentication.Password := ProxyPassword;
    Authentication.Username := ProxyUserID;
    HTTP.ProxyParams.BasicAuthentication := True;
end;

The function frmProxyUser.ShowModal asks for the ProxyPassword en
ProxyUserID.

This method works on a MS-ISA (proxy) server.

I discovered also that the Indy version (9.0.10) contains a bug when using
proxy authorization.
When you specify a faulty username and or password, the program loops
because it resets the password to nothing.
I commented out that section and my application works now perfect.

The Section commented out is:

File: idHTTP.pas
Lines 1155- 1158

  // Clear password and reset autorization if previous failed
{  if (AResponse.FResponseCode = 407) then begin
    ProxyParams.ProxyPassword := '';
    ProxyParams.Authentication.Reset;
  end;
