http encodings

[Manlio Perillo]

Hi.
RFC 2068 (Hypertext Transfer Protocol -- HTTP/1.1), introduces 4
encoding names:

identity
gzip (x-gzip)
compress (x-compress)
deflate

Unfortunately standard Python library does not includes these codecs
in the codec registry, ad example with an http_encodings package.
This will allow one to do:
data = read().encode( getheader('Cont ent-encoding').spli t() )

Actually identity codec is banal.
-gzip: it is easy to implement using gzip module (I have written the
encode and decode methods, but it should be possible to write also
StreamWriter and StreamReader classes)

-deflate: codec is the same as zlib_codec?

-compress: where can I find it?



Thanks and regards Manlio Perillo

Would be good to have these. Maybe this is useful:

Dunno, but section 3.5 of RFC 2616 (the latest HTTP/1.1 RFC) certainly
makes a distinction between the three encodings.
