Download problems?

A few people are experiencing strange problems downloading pdf files from this site. Most transfers are going normally, so I’m still trying to figure out what’s going on.

Anyone who is having download issues, please comment here and we’ll try and figure out the common theme…

So far, the only explanation I’ve had from the logs are situations where “hotlink” protection has prevented people from accessing the files: It is not an error when you are redirected from a PDF file that you bookmarked or clicked on a direct link from another site. It makes sure that people accessing the content are directed to the site itself and not just the file.

However, there seem to be other problems as well, including possible situations where the “referrer” information is not coming through properly. Any insight into this would be welcome.
