How do you set the HTTP Headers for individual files or directories in IIS7? In IIS6, you were able to right-click on a file or directory, select the "HTTP Headers" tab and then click on the "Enable content expiration" checkbox, giving three choices for when to expire the content.
The closest thing I can see in IIS7 is the "HTTP Response Headers" dialog. However, I don't know what header(s) to add to get the same functionality.
Where would I look to find out?
TIA,
