[Serusers] FW: [Sip-implementors] Whitespace after value in SIP header field

[Martin Koenig]

Hello,

I think the white space is not legal in 3261. Please take a look at the
message below.

Best regards,
Martin

Hi,

One of the headers in the posting to the SERusers mailing
list is:

Max-Forwards: 8 .

According to RFC3261 Max-Forwards is defined as:

Max-Forwards  =  "Max-Forwards" HCOLON 1*DIGIT

and DIGIT (from RFC2234) is:

        DIGIT       =  "0" / "1" / "2" / "3" / "4" / "5" / "6" /
                           "7" / "8" / "9"

So, you can have a space between the colon and the first digit
but you're not allowed any spaces after or between any digits
and you're certainly not allowed a '.' character.

Regards,

Attila
