Hi,
I am trying to create the contact-header
Contact: *; expires=0
but if I use the BNF in RFC 3261, I am not able to reconstruct it:
RFC3261:
========================================================
...
Contact = ("Contact" / "m" ) HCOLON
( STAR / (contact-param *(COMMA contact-param)))
contact-param = (name-addr / addr-spec) *(SEMI contact-params)
name-addr = [ display-name ] LAQUOT addr-spec RAQUOT
addr-spec = SIP-URI / SIPS-URI / absoluteURI
display-name = *(token LWS)/ quoted-string
SEMI = SWS ";" SWS ; semicolon
STAR = SWS "*" SWS ; asterisk
HCOLON = *( SP / HTAB ) ":" SWS
RAQUOT = ">" SWS ; right angle quote
LAQUOT = SWS "<"; left angle quote
...
========================================================
Regarding
("Contact" / "m" ) HCOLON ( STAR / (contact-param *(COMMA contact-param)))
it is possible to create a
"Contact" HCOLON STAR _or_
"Contact" HCOLON ((contact-param *(COMMA contact-param))
So, where is my error?
Best regards
Michael
