If you are on Rails 3 use redirect_to(:back)... if you are not then the only real implication is having trash hanging around in your cookie storage (if you use cookie storage.) for db storage it's meh on the space used because it's most of the time trivial but it still leaves a dirty session. So at the end of the day it depends on how thorough of a programmer you want to be. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
