An interceptor has access to application via ActionContext so it is easy to
rig up. From anywhere in your application you can manipulate an entry in
application and have the interceptor check if it matches the value it currently
has. I still think it is an unorthodox approach though. It also costs you time
as your intercept() method now has that extra check.

Subject: Re: how to re-init / update parameter of an interceptor during runtime?
thx for your reply.
actually I am not going to change the param regularly.
this is more like "just in case I want to change the setting in the future".
thx
