  We show that the standard result for the Casimir force between conducting
plates at rest in an inertial frame can be computed in light-front
quantization. This is not the same as light-front analyses where the plates are
at "rest" in an infinite momentum frame. In that case, Lenz and Steinbacher
have shown that the result does not agree with the standard result for plates
at rest. The two important ingredients in the present analysis are a careful
treatment of the boundary conditions, inspired by the work of Almeida et al. on
oblique light-front coordinates, and computation of the ordinary energy
density, rather than the light-front energy density.
