* This is the main endpoint which MoodleNet instances POST to.
|
|
|
19 |
*
|
|
|
20 |
* MoodleNet instances send the user agent to this endpoint via a form POST.
|
|
|
21 |
* Then:
|
|
|
22 |
* 1. The POSTed resource information is put in a session store for cross-request access.
|
|
|
23 |
* 2. This page makes a GET request for admin/tool/moodlenet/index.php (the import confirmation page).
|
|
|
24 |
* 3. Then, depending on whether the user is authenticated, the user will either:
|
|
|
25 |
* - If not authenticated, they will be asked to login, after which they will see the confirmation page (leveraging $wantsurl).
|
|
|
26 |
* - If authenticated, they will see the confirmation page immediately.
