public static MediaResource createCachableMediaResource(MediaResource originalMediaResource,

```
    Allow private browser caching of seconds hours. After that period the browser
    must revalidate the resource using a If-Modified-Since request header.
    Usually the answer will be a Not-Modified, but it gives us the chance
    to update CSS and Javascript files ant at least the next day users
    will be up to date as well.
    Add proxy max ager in case a proxy ignored the private cache settings.

    the bevaviour of this method is that it simply overwrites or sets a new http-response-header:
    response.setHeader("Cache-Control", "private, max-age=21600, s-maxage=21600");
    
    参数:
    originalMediaResource - the mediaResource to be cache-enabled
    seconds - determines how many seconds a browser may cache this mediaresource before revalidating it
    
    返回:
    the resulting cachable mediaresource
