Smoothing caps across rectifiers?

[Matthew S. Padden]

Hi..

    I remember there being a discussion a while ago on how it was a good
idea to put a 100n cap across the bridge rectifer in a power supply, to
prevent reverse recovery spikes. My question is this: which way should
this cap go; across the AC inputs to the bridge, or across the rectified
outputs? Or doesn't it matter?

Thanks in advance
