can anyone explain this "/user/signup = anon"

[nhhockeyplayer nashua <nh...@hotmail.com>]

I have read thru the abstract docs. I see there is a lack of meaty specific modelings of real world multi-dimensional examples... 

Can anyone explain what this does ?

I am aware of the following filters

        /**
         * SHIRO FACTORY DEFAULT FILTERS 
         * 
         * anon - anonymous filter 
         * authc - forms authentication filter 
         * basic = basic http authentication filter
         * notfound - not found filter 
         * perms - permissions authorization filter
         * port - port filter 
         * roles - roles authorization filter 
         * user - user filter
         */

But I still dont understand what the implications of the statement below means ?
Can anyone offer me a tip?

SHIRO.INI version
/user/signup = anon

JAVA LANGUAGE version
configuration.add("signup-anon", new FilterChainDefinition("/user/signup", "anon"));
