Hi
I have a query on the precedence between Expires
header and Expires in Contact in 200 OK message
As per the text in RFC3261, REGISTER message can
contain Expires in either the Expires header or the
Expires parameter in Contact header. And as per my
understanding if both are present then the value in
Expires parameter of Contact header overrides value in
Expires header. Is this correct?
In 200 OK sent in response to a REGISTER, I have two
issues
1. Since RFC 3261 clearly says that the Contact in 200
OK Must Contain Expires Parameter, this implies that
if the Contact is present, its Expires parameter
should be filled. Now my question does it mean that if
a Contact is present Expires header shall be absent in
200 OK?
2. If not then who takes the precendence expiry value
in Expires header or Expires pameter in Contact
header?
Thanks
