CookieFilter
CookieFilter specifies the name of a cookie that should be blocked from passing through EZproxy to remote web servers. CookieFilter is typically used in environments in which an application on a separate server in the same domain sets a domain-based cookie which is being "seen" by the EZproxy server, but which should not be forwarded on to any remote web servers. For example, a local cookie with a value that coordinates single sign-on across multiple servers.
CookieFilter is a repeatable, position-independent config.txt directive.
