We show that the gluon helicity inside a proton and a photon can be deduced from a knowledge of a special combination of cross sections of the semi-inclusive processese+p?e+p+p+... ande++e-?e++e-+p+p+... Such a measurement could thus be used to check the QCD prediction that the gluon helicity increases linearly with lnQ2.
