ASP.NET Cache Page for Anonymous Users

Question

Is there an easy way to cache the entire ASP.NET page for anonymous users (using authentication)?

Context: I create a site where the pages displayed to anonymous users are mostly completely static, but the same pages displayed to registered users are not.

Of course, I can do it manually using code, but I thought it might be better / easier / faster.

Answer 1

You can use VaryByCustomand use a key such as username.

Answer 2

asp.net MVC,

if (User.Identity.IsAuthenticated) {
    Response.Cache.SetCacheability(HttpCacheability.NoCache);
    Response.Cache.SetExpires(DateTime.Now.AddMinutes(-1));
    Response.Cache.SetNoStore();
    Response.Cache.SetNoServerCaching();
}
else {
    Response.Cache.VaryByParams["id"] = true; // this is a details page
    Response.Cache.SetVaryByCustom("username"); // see global.asax.cs GetVaryByCustomString()
    Response.Cache.SetExpires(DateTime.Now.AddSeconds(60));
    Response.Cache.SetCacheability(HttpCacheability.Server);
    Response.Cache.SetValidUntilExpires(true);
}

:

public class AnonymousOutputCacheAttribute : OutputCacheAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext) 
    {
       if(filterContext.HttpContext.User.Identity.IsAuthenticated)
          return;

        base.OnActionExecuting(filterContext);
    }  
}
