Transition from Http.PTextSb to Http.HttpSb

Provides instructions for replacing deprecated PTextSb method calls with HttpSb. Delphi DLL

//  ------------------------------------------------------------------------
//  The PTextSb method is deprecated:

responseObj := CkHttp_PTextSb(http,verb,url,sbRequestBody,charset,contentType,False,False);
if (CkHttp_getLastMethodSuccess(http) = False) then
  begin
    Memo1.Lines.Add(CkHttp__lastErrorText(http));
    Exit;
  end;

//  ...
//  ...

//  Do the equivalent using HttpSb.
//  Your application creates a new, empty HttpResponse object which is passed 
//  in the last argument and filled upon success.
