Indy 9.0.18
BCB6

I am able to login to the web page fine.
If I first use an invalid password, the connection is properly rejected.  After a rejection, issue
an IdHTTP->Disconnect();.
Correcting the password still results in a rejection. I must close the application and restart it
to use the correct the password and log-in.
What must I do to restart the connection fresh?

No ideas?

Here's stripped down some example code.

if(IdHTTP->Connected())
  IdHTTP->Disconnect();
IdHTTP->Request->BasicAuthentication = true;
IdHTTP->Request->Username = "admin"; // you can add an edit box to enable additional users
IdHTTP->Request->Password = EdtPassword->Text;
// This overrides the default Mozilla 3 signature which will cause an error
IdHTTP->Request->UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; Q312461; .NET CLR
1.0.3705)";
IdHTTP->HandleRedirects = true;	// Prevents the 302 error because of redirection
// Check for a password
if ( EdtPassword->Text.Length() < 1 )
{
  MessageDlg("Please enter a password.", mtError, TMsgDlgButtons() << mbOK, 0);
  EdtPassword->SetFocus();
  return;
}
try
{
  AnsiString S = AnsiString("http://")+EdtURL->Text+":"+EdtPort->Text+AnsiString("/");
  AnsiString Resp = IdHTTP->Get(S);
  // Remove newline characters for compatability between EPCR and LPC
  UpdateStatus(Resp);
}
catch ( Exception &E )
{
  IdHTTP->Disconnect(); // If the password is invalid, I get the error here.  
                        // I cannot retry with a new password until the app is closed 
                        // and restarted. 
  Application->ShowException(&E);
}
...

Try upgrading to the 9.0.50 snapshot and see if the problem still persits.

I am assuming that you already removed Indy 8 from your machine?

Try also resetting the Authentication property:

    if( IdHTTP->Request->Authentication )
        IdHTTP->Request->Authentication->Reset();

Or:

    if( IdHTTP->Request->Authentication )
    {
        delete IdHTTP->Request->Authentication;
        IdHTTP->Request->Authentication = NULL;
    }

Also, rather than waiting for a rejection-related exception to be thrown,
you can use the OnAuthorization event to dynamically change the username
and/or password.  If you set the Handled parameter to True, then TIdHTTP
will automatically retry to login with the new values.
