+# Provides the ability to have session cookies for your Rails app calculated

+# In your environment.rb file (or in the environments/*.rb file of your choice),
+# do something like the following:
+#
+#   CGI::Session.expire_after 1.month
+#
+# Session cookies will then expire one month after the session was created. This
+# differs from the usual session cookie behavior in that the expiration date is
+# not a fixed time, but rather relative to the current time.
