IPFS might well be appropriate for publication in its whole of HTML-pages. But there is a problem. MHTML is not possible to place because IPFS is not able to give this format with mime-type: message/rfc822.

For example: http://gateway.ipfs.io/ipfs/QmfHtsEyXGdJm6Yo4frKLdKyDKT5G6ubECfVLnvkVUkscM

Is there any solution to this problem?
