Caching WCF Service based on output

Question

I have this service:

public  bool Inquiry( string Plaque)
{

}

As you can see the output of my service is true or false for a specific plaque. I want to cache the output that is true for 15 days. I mean, when the result was true for specific plaque, I need to cache this data,so if again the system call my service for that plaque, it should be returned by cache system. Is it possible?

Best regards.

if (_inquiryview.ValidTest == "1")
        {
            HttpContext context = HttpContext.Current;
            HttpCachePolicy cachePolicy = HttpContext.Current.Response.Cache;
            cachePolicy.SetCacheability(HttpCacheability.ServerAndPrivate);
            cachePolicy.SetExpires(DateTime.Now.AddDays(15));
            cachePolicy.VaryByHeaders["Accept"] = true;
            cachePolicy.VaryByHeaders["Accept-Charset"] = true;
            cachePolicy.VaryByHeaders["Accept-Encoding"] = true;
            cachePolicy.VaryByParams["*"] = true;
            cachePolicy.SetValidUntilExpires(true);
        }
