ASP.NET and the output cache - how can I see if it works?

Question

Problem . I have an ASP.NET website and I do not believe that my code correctly gets OutputCached. I use IIS7 performance counters to show me hits or skip a second.

---

I have a simple ASP.NET MVC website. I use the built-in magic of ASP.NET output cache.

Here is a sample code: -

[AcceptVerbs(HttpVerbs.Get)]
[ApiAuthorize]  // <-- this checks the querystring for a "key=1234". 
                // Doesn't find it, then it throws a 401 NOT AUTH exception.
[OutputCache(CacheProfile = "HomeController_Foo")]
public ActionResult Foo(string name, byte? alpha, byte? beta)
{
}

therefore this means that each url request may look like this: -

• http://www.mydomain.com/Foo?name=hello+word&key=1234
• http://www.mydomain.com/Foo?name=hello+word&alpha=1&key=1234
• http://www.mydomain.com/Foo?name=hello+word&alpha=1&beta=2&key=1234

Now notice how I got OutputCache referencing the configuration file? here it is...

<caching>
    <outputCacheSettings>
        <outputCacheProfiles>
            <add name="HomeController_Foo" duration="3600" varyByParam="key;name;alpha;beta"/>
        </outputCacheProfiles>
    </outputCacheSettings>
</caching>

Nothing complicated ...
