It sounds like you want the services of the System.Uri class (http://msdn.microsoft.com/en-us/library/system.uri.aspx). I'm guessing that at some point you have to decide whether or not you are going to allow or disallow a request based on the URI, in which case you will want logic similar to the following:

Uri uri = new Uri("http://www.google.co.uk/somepage.html");
if (uri.Host.ToLower().EndsWith("google.co.uk"))
{
    // Do something
}

Experiment with something like that. Things to note are that:

• If you check to see if the host equals "www.google.co.uk" then this would still mean that other subdomains (e.g. "www3.google.co.uk") wouldnt be blocked.
• If you check to see if the host contains "google.co.uk" then you risk blocking others whose subdomain contains (for stupid reasons) someone elses url, for example "google.co.uk.MyDomain.co.uk" which is still a valid (if stupid) subdomain under the "MyDomain.co.uk" domain.
