ASP.NET Web API OutputCache

A simple filter bringing caching options, similar to MVC's "OutputCacheAttribute" to Web API ApiControllers.

Usage:

    [WebApiOutputCache(duration: 120)]
    public IEnumerable<string> Get()
    {
        return new string[] { "value1", "value2" };
    }

    [WebApiOutputCache(cacheProfile: "cache2min")]
    public string Get(int id)
    {
        return "value";
    }
