Is it possible to have a Site without Site Definition

Question

I am working on a portal and have a site/web and I am trying to find out what site definition its using, I tried this code to find out, it does give me a site template ID and Master page URL, but it Site definition is blank, I was wondering if its possible that there is a site without any site definition.

I am using this code

   using (SPSite mySite = new SPSite(PageUrl))
        {
            using (SPWeb web = mySite.OpenWeb())
            {
                Console.WriteLine("Site definition: {0}", web.WebTemplate); // BLOG
                Console.WriteLine("Web template ID: {0}", web.WebTemplateId); // 9
                Console.WriteLine("Master Page : {0}", web.MasterUrl); // 9
            }
        }

it did worked for me many times before tho.

It is not possible. All webs have site definition. The name of definition you can get by this code:

string id = string.Format("{0}#{1}", web.WebTemplate, web.Configuration)

To see what definition is used you can compare result string with values in this post.
