Ranger header missing "bytes"

[makuk66]

I use Pylons with Paste 1.4.2. When requesting a URL to a file in the public/ directory, Paste responds with:

200 OK Connection: close Accept-Ranges: bytes Content-Range: 0-7218/7219

The Ranger header should have the word "bytes" and a space before the byte range spec according to  http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.16

A user reported that this can cause problems with the Polipo proxy.

One quick fix is to change httpheaders.py:

retval = "%d-%d/%d" % (first_byte, last_byte, total_length)

to:

retval = "bytes %d-%d/%d" % (first_byte, last_byte, total_length)

which duly produces "bytes":

Content-Range: bytes 0-7218/7219

but I have not verified if that has any non-intended side-effects.
