Are commas allowed as a separator of multiple cookies in a cookie header?
I am running an application in wildfly-11.0.0.Final and another application is making a
request with two cookies, JSESSIONID and JSESSIONIDSSO. It is sending these as
JSESSIONIDSSO=jIEqQ-kTedwXrvqm9CBACBg8QlCXzJKILwCftnaV,
JSESSIONID=lDA5h47Pk_jrnIwAshNsQ7Ot269XyVSTR1mwYNEL.localhost
which then seems to be parsed into a single cookie
JSESSIONIDSSO=jIEqQ-kTedwXrvqm9CBACBg8QlCXzJKILwCftnaV, JSESSIONID
which of course does not work for the authentication so the request fails. This seems to
be a failure in parsing the original cookie string. There is a bit of confusion in this
area in the RFCs as the earlier ones allowed comma as a separator but the most recent,
RFC-6265, does not. Undertow should probably allow a comma separator for backward
compatibility with older implementations.
Thanks
