  A simple and elegant model, based on Reggeized t-channel exchanges is
succesful in reproducing the main features of all existing data of the
reactions ep->eKLambda and ep->eKSigma. In particular, the original way gauge
invariance is taken into account is found to be essential to describe the ratio
between the Coulomb and the Transverse cross-sections at large Q2 that has been
measured recently at JLab.
