In HTTP the meta information is in the HTTP header. This is all very
well except the that the server is just guessing. It is serving a
standard header for all documents with a given extension.  The meta
info needs to be in the document itself. Ditto for MIME type.

If  the document is transported compressed e.g. SPDY 
http://mindprod.com/jgloss/spdy.html 
and fluffed on the other end, then that compression is not part of the
document meta data. If it is kept around compressed, e.g. zip, then it
is.

When it arrives, and is saved on disk, the meta info needs to be
retained, so that an editor knows how to deal with it. The only way
you can do that is is if the meta info is embedded in the file.

The half-assed way we do things depends on the fact encodings are not
all that different.  You can get it wrong and still muddle through.
