Then I go to Lenya, click on the link in IE/Win with Acrobat 7 combination and the file
is working. Thank God, I think to myself. I finally solved the problem. So then I
check out the live environment - same computer, same setup. "The file is corrupt or
damaged and cannot be repaired." So what the heck? It doesn't make any sense - it
seems to be completely random. I'm serving the same file on the same computer and same
setup with the only difference is one is in the authoring environment and the other is in
the live environment and the results are different. Then some files now work in the live
environment and others do not.
Just as an example, go ahead and check out this page:
http://alumni.hiram.edu/events/homecoming.html. Click on the big link using
IE/Win with Acrobat Reader as plugin and see what you get. I continue to get
file damaged errors, but some people say they can see it fine. It just seems
so random. Anyone have any ideas? I'm feeling pretty helpless on this one...
Jon, we had the same problem a couple of years ago, unfortunately I
can't find the solution from that time. It was Apache-based anyway, and
involved telling Apache to do a workaround in the http headers for this
IE+Adobe problem. I can't remember if the workaround involved changing
the expires header or not; whatever the workaround was, it no longer
seems necessary (we did a new system installation a few months ago) and
google can not find the pages I found on that subject back then :/
So I'm sorry I can't really help you, but what I would suggest you do:
- the apparent "randomness" in Web stuff usually comes from caching
problems. Whatever you may have set in the server, I suggest that before
any client test, you clear the browser's cache
- regarding differences in environments, be sure to know the whole chain
of software in both situations. Unfortunately, any piece of software
might change your http headers on the way; that includes things like
proxies and sometimes firewalls, too.
