|
=back |
url to display by including in an iframe within a |

LON-CAPA page which has a standard LON-CAPA inline menu. |

=cut |
=item $brcrum |
|
|
|
breadcrumbs for unregistered urls |
|
(i.e., external resources in Supplemental Content). |
|
|
|
=item $absolute |
|
|
|
contains protocol (http or https) followed by |
|
the hostname, if menu items in the standard LON-CAPA |
|
interface created by the call to loncommon::start_page() |
|
within &wrapper() need to use absolute URLs rather than |
|
relative URLs. |
|
|
|
That will be the case where an external resource has been |
|
served from port 80, when the server customarily serves |
|
requests using Apache/SSL (i.e., port 443). mod_rewrite |
|
is used to switch requests for external resources and |
|
the syllabus: /public/<domain>/<courseid>/syllabus |
|
(which might also point at an external resource) |
|
from https:// to http:// where the the URL of the remote site |
|
specified in the resource itself is http://. |
|
|
|
This is done to avoid default mixed content blocking |
|
in Firefox 23 and later, when serving from Apache/SSL. |
|
|
|
=item $is_ext |
|
|
|
true if URL is for an external resource. |
|
|
|

|
|
|
true if URL is for a PDF (based on file extension). |
|
|
|
=item $title |
|
|
|
optional. If wrapped item is a PDF, and $env{'browser.mobile'} |
|
is true, a link to a PDF is shown. The "title" will be displayed |
|
above the link, but if not provided as an arg, $env{'form.title'} |
|
will be used, otherwise, the filename will be displayed (unless |
|
hidden URL set for the resource). |
|
