Javascript is client-side - only way to detect it is to have a page
send back information (post/get). What might work easiest is to have
jquery look for a given cookie upon page render, and if it doesn't
find it, then do an ajax call to the server. On the server side,
initiate a session for the user, set "using_javascript" to false and
update to true if you receive the ajax call.

That aside, why would you need to know in the backend if a user is
running javascript?
