# This is a mod_python handler program. The correct way to call it is to have
|
|
23 |
# Apache send all requests to be handled by the module 'dispatch'.
|
|
24 |

25 |
# Top-level handler. Handles all requests to all pages in IVLE.
|
|
26 |
# Handles authentication (not authorization).
|
|
27 |
# Then passes the request along to the appropriate ivle app.
