How to specify Expires header for static resources in ASP.NET MVC?

Thanks to author of the post on Stackoverflow.com. He posted a link to the broadest description of the ways the header “Expires” can be specified for static resources. Here it is – clientCache.

Finally, I put the following setting in my web.config:

<system.webServer>
<staticContent>
<!–Never Expires–>
<clientCache cacheControlMode=”UseExpires” httpExpires=”Sun, 07 Apr 2047 00:00:00 GMT” />
</staticContent>
</system.webServer>

There is a point to notice. It seems virtual web-server which is ran under VS ignores such setting. I could found a reason why it’s so. If somebody point me out to the reason or solution I’ll be very appreciated.
