Recent results concerning the light-cone gauge are reported. In particular we revisit the nonsinglet Altarelli-Parisi kernel in the leading-log approximation. Ultraviolet and infrared singularities are neatly disentangled thanks to the Mandelstam-Leibbrandt prescription in the vector propagator. A new interpretation emerges of real'' and virtual'' diagram contributions. Then we exhibit the one-loop renormalization of the composite operator [ital A][sub [mu]][sup [ital a]](0)[ital A][sub [nu]][sup [ital b]](0) as a first step towards full control of gauge-dependent insertions.
