Hi, are you sure of that? In SIP protocol (which inherits from HTTP
grammar) a header parameter (;foo=lalala) can contain spaces anywhere
(before/after the ";", before/after the "="). So something like:

   Sec-WebSocket-Extensions: foo  , bar  ; baz = 2

is valid.

However it's not clear for me wheter in this example "baz=2" is a
header param or a param just for the value "bar". In the last case it
would mean a specific header syntax, so spaces could be not allowed.
Could you please point to the ABNF grammar you meant?

Thanks.
