This interface represents an Accept request-header. It can be used in to
specify media-ranges which are acceptable for the response. AcceptHeaders
can be used to indicate that the request is specifically limited to a small
set of desired types. The specification of the acceptable media
is split into type and subtype.
An AcceptHeader may be followed by one or more parameters applicable to the
media-range. q-values allow the user to indicate the relative degree of
preference for that media-range, using the qvalue scale from 0 to 1. (If no
q-value is present, the media-range should be treated as having a q-value of
1.)
If no AcceptHeader is present in a Request, the server SHOULD assume a media
of type "application" and subType
"sdp". If an AcceptHeader is present, and if the server cannot send a
response which is acceptable according to the combined Accept field value,
then the server should send a Response message with a NOT_ACCEPTABLE
status code.
For example:
Accept: application/sdp;level=1, application/x-private, text/html
