two issues popped up recently during the internal discussions, where
getSize() might be handy, possible HTTP Range support at the custom MBW
level, and in cases where Content-Length is explicitly expected on the
client side, so why returning something different than -1 from getSize()
won't work with GZIP and such, the users should still have the option to
return a positive value when it is known it will work

Thanks, Sergey
