There is no code in Struts that ever creates a request scope attribute
named "experiments" on its own. That has to be coming either from
code in one of your actions actually storing it there, or because
you've decared "experiments" to be a form bean and then executed an
action that references that form bean name somewhere (which would
trigger the normal Struts behavior to create the form bean for you).
