Re: Introducing TLS

Quoting Sam Berlin <[email protected]> from ml.gnutella.dev-forum:
:  The X-Alt header is changed so that "tls=##" is written prior to any of
:the
:  locations are listed.  '##' is the hexademical representation of the
:byte[]
:  that describes which of the following alternate locations can accept
:TLS.

This specification is confusing.  It looks like one cannot send more
than 8 addresses in X-Alt.

'##' does not stand for 2 hex chars, but rather a complete bit array
in big-endian format, where bit 0 represents the first address,
bit 1 the second address, etc..

So in a list of 17 hosts where only the 16th (i.e. the last but not least)
host can support TLS, this is bit #15 (numbering starts at 0), you would say:

	tls=8000,

at the beginning of the X-Alt field, where indeed only the bit #15 is set.

Thanks for clarifying the specs accordingly.
