My apologies, I wrote from memory.

Less than a month ago I implemented:

     Property AllowRedirect : Boolean Read FAllowRedirect Write FAllowRedirect;
     // Maximum number of redirects. When this number is reached, an exception is raised.
     Property MaxRedirects : Byte Read FMaxRedirects Write FMaxRedirects default DefMaxRedirects;
     // Called On redirect. Dest URL can be edited.
     // If The DEST url is empty on return, the method is aborted (with redirect status).
     Property OnRedirect : TRedirectEvent Read FOnRedirect Write FOnRedirect;
     // Authentication.
     // When set, they override the credentials found in the URI.
     // They also override any Authenticate: header in Requestheaders.
     Property UserName : String Read FUserName Write FUserName;
     Property Password : String Read FPassword Write FPassword;
     // If a request returns a 401, then the OnPassword event is fired.
     // It can modify the username/password and set RepeatRequest to true;
     Property OnPassword : TPasswordEvent Read FOnPassword Write FOnPassword;
     // Called whenever data is read from the connection.
     Property OnDataReceived : TDataEvent Read FOnDataReceived Write FOnDataReceived;
     // Called when headers have been processed.
     Property OnHeaders : TNotifyEvent Read FOnHeaders Write FOnHeaders;

OnDataReceived and OnHeaders is probably what you are looking for. Sorry for the fuzzyness.
