So this is a convenient way to bring us back to the other half of the
issue which we do not seem to have discussed yet. When the syntax was
defined that allowed ?headers:
Headers: Header fields to be included in a request constructed
from the URI.
Headers fields in the SIP request can be specified with the "?"
mechanism within a URI. The header names and values are
encoded in ampersand separated hname = hvalue pairs. The
special hname "body" indicates that the associated hvalue is
the message-body of the SIP request.
What usage did the SIP WG envisage for this, and thus what semantics
did they define for that usage.
Is it appropriate to assign new semantics to such usage?
I believe we were confused about the differences between headers and
URI parameters and didn't quite get the "?" notation used with HTTP
cgi-bin.
I'm not certain there was any actual confusion here when we settled on
that syntax originally. RFC 2396 (which was current at the time,
although it has been superseded by RFC 3986) describes this portion of a
URI as nothing more than: "The query component is a string of
information to be interpreted by the resource." I think SIP's use is
consistent with that.
Additionally, RFC 2368 gives clear and strong precedent for precisely
this interpretation of the query component of URIs.
