  Results for response functions for kaon electroproduction on the proton are
presented. A tree-level hadrodynamical model is adopted and it is shown that
some of the electroproduction response functions are particularly powerful with
the eye on gaining control over the parameterization of the background
diagrams. The existing data set for the p(e,e'K+)Lambda reaction appears to
rule out the use of a g_{K+ Lambda p} coupling constant beyond the boundaries
of softly broken SU(3) flavor symmetry. Also the use of soft hadronic form
factors, which has been proposed as a valid alternative for a hadrodynamical
description of the p(gamma,K+)Lambda data in the resonance region, seems to be
disfavored by the magnitude of the measured p(e,e'K+)Lambda cross sections.
