The first time someone tries to load one of these URL nothing happens. When someone tries to load another one, it loads just fine. When they re-try the first one, it loads. We are banging our heads against the wall here at Catholic Pamphlet Central. Networking issue? Port issue? IE PDF plug-in? Invalid HTTP headers?

I don't have IE to test from, but it's been my experience that in past versions of IE, it would use the file's extension no matter what the mime-type sent was. I'd first see if you can trick IE ... it looks like Fedora doesn't like you sending extra stuff in PATH_INFO, so you might have to abuse QUERY_STRING for this: http://fedoraprod.library.nd.edu:8080/fedora/get/CATHOLLIC-PAMPHLET:1000793/PDF1/?filename.pdf http://fedoraprod.library.nd.edu:8080/fedora/get/CATHOLLIC-PAMPHLET:1000793/PDF1/?file=filename.pdf If either of those work fine in IE, but the first one doesn't, that's the problem. I don't know what's possible in Fedora, so I don't know if it's possible to do some URL re-writing so it'd always serve something that IE accepts as a PDF. If you could insert an extra HTTP header, you might be able to trick it with Content-Disposition, but that'll also tell some browsers to download the file rather than display it themselves: http://www.ietf.org/rfc/rfc2183.txt -Joe
