        wxStreamBase::GetSize. However there is a
        limitation: in HTTP protocol, the size is not always specified so sometimes
        @c (size_t)-1 can returned ot indicate that the size is unknown. In such
        case, you may want to use wxInputStream::LastRead
        method in a loop to get the total size.
        
        @returns Returns the initialized stream. You must delete it yourself once
                 you don't use it anymore and this must be done before
                 the wxHTTP object itself is destroyed. The destructor
                 closes the network connection. The next time you will
                 try to get a file the network connection will have to
                 be reestablished, but you don't have to take care of
                 this since wxHTTP reestablishes it automatically.
