ASP.NET MVC - compression + caching

Question

I've seen a number of options for adding GZIP/DEFLATE compression to ASP.Net MVC output, but they all seem to apply the compression on-the-fly.. thus do not take advange of caching the compressed content.

Any solutions for enabling caching of the compressed page output? Preferably in the code, so that the MVC code can check if the page has changed, and ship out the precompressed cached content if not.

This question really could apply to regular asp.net as well.

Answer 1

[Compress]
[OutputCache(Duration = 600, VaryByParam = "*", VaryByContentEncoding="gzip;deflate")]
public ActionResult Index()
{
    return View();
}

Answer 2

You could create a Cache Attribute:

public class CacheAttribute : ActionFilterAttribute
{
    public override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        HttpCachePolicyBase cache = filterContext.HttpContext.Response.Cache;

        if (Enabled)
        {
            cache.SetExpires(System.DateTime.Now.AddDays(30));
        }
        else
        {
            cache.SetCacheability(HttpCacheability.NoCache);
            cache.SetNoStore();
        }
    }

    public bool Enabled { get; set; }

    public CacheAttribute()
    {
        Enabled = true;
    }
}
