disable object caching?

hi -

does rails cache code by default?

i have some lib/user classes, and when i add new methods i have to restart the webserver for them to show up. that hardly seems expected behavior? it makes each test/run cycle longer than compilling... is there a way to turn off caching?

i found this note: # Note: To turn off all caching and sweeping, set Base.perform_caching = false.

but not sure where to put that code!

tx!
