Subject: RE: Seeing who's logged in - but a question on application
variab les between applications
is it possible to read variables from one application from another...
lets say you had an administrator page that was separate from the main site,
thusly a separate application name, but you wanted to see who was on...
could you actually read the mainsite.appliaction.user struct from the admin
site??
so far, i have used 5-10 min cached database queries to do this... but
wonder about the above... could have other value as well...
