When I run the Google Chrome Page Speed on one of the web sites I created, I got the following warning for lots of static resources (.js, .jpg, .png, .css files);
The following cacheable resources have a short freshness lifetime. Specify an expiration at least one week in the future for the following resources: http://www.example.net/Content/App_Icons/Exported/MC900304631.png (expiration not specified)
My app is an asp.net and asp.net mvc hybrid app and running on windows server 2008 r2, IIS 7.5.
How can I enable that feature? Couple of moths ago, I heard something about eTag bhut don't if it has anything to do with that. could provide examples or good resources on this?
