A question about "shuffling" online

[Voltaire]

In a B&M hold'em game if you fold your hand you usually have the dubious pleasure of seeing if the flop, turn and river would have helped your hand. My question is, is this true playing over the Internet?

I tried to search for this, since I suspect it's been asked and answered, but I couldn't find it.

My point is that perhaps the cards are randomized again after the first round of betting for security reasons.

Anybody know the answer to this?

Thanks.
