We start with study of the meson form factor F{sub M} (Q{sup 2}) constructed using recently proposed holographic light-front wave functions. We find that its asymptotic behavior is generated by soft Feynman mechanism rather than by short distance dynamics. In this scenario, both hard and soft contributions are present, and the ''observed'' quark counting rules for hadronic form factors is an approximate and transitional phenomenon resulting from long-distance dynamics, Feynman mechanism in its preasymptotic regime.
