Problems downloading files with CACHE-CONTROL header

I'm looking in both routes, but the problem is that while Microsoft does have some documentation on the subject, like the example you gave above, every article of their own that I've come across has been specific to a certain type of scenario. Worse yet, the resolution to each is a patch or specific fix of some kind on the browser side. Because we are a financial institution and the application is for customers, we cannot enforce a requirement that all users using IE (90% or more, no doubt) must install a patch not required by Microsoft in critical updates. In other words, this failure will occur 100% of the time with users running IE browsers unless they install a specific patch, and of course I can't place such a requirement on all of our customers.

 

 

What I'm hoping to find here is the possibility that someone who understands the cache-control header might also understand the way IE works when it comes to that header. For example, does anyone know of an effective way that I might apply those headers to common traffic while excluding file downloads? I've learned a lot about iRules since we moved our boxes to 9.x, but I still have much to learn about HTTP overall.
