how django discovers changed sources

Dave

hi,

I started playing with django and accidentally discovered that it
restarts the server once a source file is touched.

does it use some python's feature or just scans for changs on its one?
sources?

any idea?

That is the behavior of the development server. When you are writing
your application, you don't want to have to manually restart the
server every time you change a file. On apache it obviously doesn't
do that.

django.utils.autoreload provides the functionality.
