  We investigate small-x QCD effects in forward-jet production in deep
inelastic scattering in the kinematic regime where the virtuality of the photon
and the transverse momentum of the jet are two hard scales of about the same
magnitude. We show that the data from HERA published by the H1 and ZEUS
collaborations are well described by leading-logarithmic BFKL predictions.
Parametrizations containing saturation effects expected to be relevant at
higher energies also compare well to the present data. We extend our analysis
to Mueller-Navelet jets at the LHC and discuss to what extent this observable
could test these small-x effects and help distinguishing between the different
descriptions.
