static content not caching in Asp.net MVC

Question

I want to cache all my static content of mvc application.

I Added Web.config file like this in the Content folder

I got proper response header from my server.

Even after receiving the header with max-age attribute, The next Request to the server goes with Cache-Control: no-cache

This again retrieve the whole data.

It is not caching.

I want to know What am i missing here. Thanks in advance.

The no-cache in your screenshot is a request header not a response header.

It is likely being issued by your browser in response to you forcing a refresh (Control-F5). The browser is effectively saying 'please get me fresh data, I don't want the cached data'. The server-side can't control this - the client is the one making the request.

If you aren't forcing a refresh then you may have disabled your browser cache (e.g. https://stackoverflow.com/a/7000899/34092 ).
