I have this exact rule applied to one of our apps (and I've tried adding HTTP::version "1.1" as well), and it works great for the most part... until a user attempts to download a file in IE. I've found a number of sites that talk about problems when downloading files in IE when the CACHE-CONTROL header is present, but I find it hard to believe that this long into the existence of IE it's still just a fact that IE, downloads, and that header cannot ever co-exist. Has anyone else ever run into this?
When a user attempts to download a file, the error is something like this:
Internet Explorer cannot download [file] from [server host name].
Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later.
Any ideas?
