My site uses PHPBB as a forum, and we would like to use it as a place to store and share large files up to 1gb.
I'm afraid that if one of our hotlinks is overly shared, it will cause problems with overly high usage of bandwidth and resources.
For example the page: http://forums.pcgamingwiki.com/viewtopic.php?f=23&t=60 contains the hotlink: http://forums.pcgamingwiki.com/download/file.php?id=4
What is a good way to prevent hotlinking in PHPBB? Can I get the hotlink to redirect to the forum post so that viewers will see our advertising, which will help pay for bandwidth? Is it possible to restrict files to be downloaded by logged in users only?
