I am working on a ASP.NET 2.0 web site that has some PDFs that users can
download. I'm using an HTTP module to see if the user has permission to view
the PDF before loading it. This all works great. The problem is that once
the PDF has been allowed through to the browser, it won't be denied to the
next user. So, if one user is allowed to see it and then a user who is not
allowed to see it uses the same browser, it comes through for them. If I
clear the cache on the browser, it works again. I think that once the PDF
doc comes through, the browser is caching it. How can I prevent this caching
from my web code? Thanks.
