Clearing session

gistfile1.rb

# something trivial but might be helpful if you want to implement clearing the session hash when the user presses the
# Back button 

# used in IQF project when the email contact link on top right of page has to show the title of current page

def clear_session
    response.headers["Cache-Control"] = "no-cache, no-store, max-age=0, must-revalidate"
    response.headers["Pragma"] = "no-cache"
    response.headers["Expires"] = "Fri, 01 Jan 1990 00:00:00 GMT"
end

def my_own_controller_action
.....
  clear_session
  # rest of code

end



# or use it in a before_filter
# e.g. before_filter :clear_session
