.obj question

Hi, sorry to pollute the list with this stupid question :)

is there any convention for differentiating between frontface and backface in
wavefronts .obj model format if normals aren't provided? (I have a couple
models with only vert lists and face lists, and my viewer is drawing half the
polygons with the wrong face). All the pertinant links I could find were either
dead or didn't go into detail :/ Any help would be greatly appreciated, thanks
