"Allow: 204" is not related to previews. It tells the ICAP server that
it's OK to respond with 204 at any time, even outside of the preview.

The preview is signalled by the "Preview: nnnn" header, and implicitly
requests the ICAP server to respond with 204 or 100 at the end of the
preview to continue the transaction or possibly a syntesised response
replacing the original message.
