In normal usage, no. Ruby supports garbage collection, meaning that
memory allocated for objects no longer reachable will be reclaimed.

You are talking about two very different things. Here, I think you're
digressing into CGI. And in that case, you should see the Sessions
section of this article: http://www.rubycentral.com/article...

Management of CGI session data is wholly distinct from Ruby's
management of objects in general. Ruby the language knows nothing about
CGI, CGI sessions, or persistent data from those sessions. These are
implemented via the external CGI library.
