Resources FAQ

How can I enable students using IE7 to view PDF files?
Check the force download box on the update page. (This work-around is necessary because of the way IE7 handles PDF files.)
How can I stop uploaded files from being cached when I update them?
By default, Moodle adds a "cache-control" header to all files that is sends. The default period is 24 hours. You can reduce this or eliminate it entirely (set to zero) by adding the following line to your config.php (default value shown).
$CFG->filelifetime = 86400;
