I have the following line in my apache config for a website:

Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"

Part of the website generates CSVs that can be downloaded but in IE, with this line present in the config IE presents the following error:

Internet Explorer cannot download admin/ from wwww.domain.com
Internet Explorer was not able to open this Internet site.  The requested site is either unavailable or cannot be found.  Please try again later.

Is this a known issue with IE and is there a known fix? Or is there a way to only implement the cache control on certain pages?

If I comment out that line it works fine in IE.

Can I add something like this to the < head > of pages that require it instead of the apache config line?

Looks like it's the 'no-cache' header that's causing the problem:

Can you set an Expires header instead?
