When passing variables to the new page, do you always encode them? I have not yet learned how to do this but was just wondering what sort of security hazards there are if you don't encode them.
yes, that's an encoding of sorts... you can create your own versions of this, or use existing ones.. even play around with existing ones to make them your own.. although it looks like 'token' is there session id system...
depends on how secure you care for that data to be.. the more secure you want it, the more encryption/protection you'll want/need on it. however, the more secure you go, the farther away from url parameters you get.
