Content handler for requests for: /adm/wrapper/... |
|
used for content to be displayed in an iframe, or launched in a separate tab |
|
or window via a link. The target URL is extracted from the requested URL, by |
|
removing the /adm/wrapper prefix. |
|
|
|
The target URL will typically be a PDF served from the current server, an |
|
external resource URL served from a different server, or an external tool |
|
(from an LTI Provider) launched from LON-CAPA (as LTI Consumer) and launched |
|
via a link. |
|
|
|
If the request included forceedit in the query string, and the requester has |
|
rights to modify course content, then the editor will be didplayed to allow |
|
changes to be made to the resource (e.g., change the URL of the external resource, |
|
or change the setting for the external tool instance. |
|
|
|
If not in edit mode, then the wrapper() subroutine will be called to generate the |
|
standard LON-CAPA inline menu, and then either a link to launch a separate tab or |
|
window, or an iframe to display the content inline. |
