Symptoms

Clients sending a malformed cookie (that is, a space character that precedes the persistence cookie) might prevent the parsing of a valid persistence cookie.

Impact

Persistence is ignored.

Conditions

HTTP request contains malformed cookie value that occurs before the BIG-IP system persistence cookie, For example: Cookie:foo=bar =bar; BIGipServerhttp=60361226.20480.0001

Workaround

None.

Fix Information

Cookie values containing space character are parsed properly.
