解説
このクラスを使用すると、呼び出し元が特定の Web サイトであることを確認できます。サイト ID は、HTTP、HTTPS、および FTP のプロトコルの付いた URL からのコードだけで定義されます。URL のプロトコルの後ろの "//" から次の "/" までの間に文字列がある場合は、その文字列がサイトを表します。たとえば、URL https://www.fourthcoffee.com/process/grind.htm の www.fourthcoffee.com がサイトです。ポート番号は除外されます。URL が https://www.fourthcoffee.com:8000/ の場合、サイトは www.fourthcoffee.com:8000 ではなく www.fourthcoffee.com になります。
サイトには、完全に一致する文字列か、ドット区切り文字の前にワイルドカード ("*") を付けた文字列を指定できます。たとえば、サイト名として文字列 *.fourthcoffee.com を指定すると、fourthcoffee.com と www.fourthcoffee.com の両方と一致します。ワイルドカードを使用しない場合、正確に一致するサイト名だけが見つかります。サイト名として文字列 * を指定した場合、任意のサイトと一致しますが、サイト証拠のないコードとは一致しません。
注意 SiteIdentityPermission は、URL と IP アドレスを含め、サイトへのすべてのパスに対するアクセス許可を与えます。サイトへのアクセスを Deny によって拒否するには、そのサイトへの有効なパスをすべて Deny によって拒否する必要があります。たとえば、www.forthcoffee.com の IP アドレスが 192.168.238.241 の場合、www.forthcoffee.com へのアクセスを Deny によって拒否するには、www.forthcoffee.com、192.168.238.241 を含め、そのサイトにアクセスために使用できるすべてのパスを Deny によって拒否する必要があります。複数のパスを使用する場合は、 PermitOnly と Deny を組み合わせて使用することをお勧めします。この詳細および Deny で PermitOnly を使用する場合の詳細については、「 Deny 」の Canonicalization Problems Using Deny を参照してください。
