When a program is paused, the Debug Console panel (which is different from the "Python Debug Console" in the Terminal panel) lets you experiment with expressions and try out bits of code using the current state of the program. In that case, Django will do one the following two things: If DEBUG mode is set to True then Django template system will throw TemplateDoesNotExist exception. SECURE_REDIRECT_EXEMPT = [r'^no-ssl/$', …].
