| /** |
| * This class provides HTTPS client URL support, building on the standard |
| * "sun.net.www" HTTP protocol handler. HTTPS is the same protocol as HTTP, |
| * but differs in the transport layer which it uses: <UL> |
| * |
| * <LI>There's a <em>Secure Sockets Layer</em> between TCP |
| * and the HTTP protocol code. |
| * |
| * <LI>It uses a different default TCP port. |
| * |
| * <LI>It doesn't use application level proxies, which can see and |
| * manipulate HTTP user level data, compromising privacy. It uses |
| * low level tunneling instead, which hides HTTP protocol and data |
| * from all third parties. (Traffic analysis is still possible). |
| * |
| * <LI>It does basic server authentication, to protect |
| * against "URL spoofing" attacks. This involves deciding |
| * whether the X.509 certificate chain identifying the server |
| * is trusted, and verifying that the name of the server is |
| * found in the certificate. (The application may enable an |
| * anonymous SSL cipher suite, and such checks are not done |
| * for anonymous ciphers.) |
| * |
| * <LI>It exposes key SSL session attributes, specifically the |
| * cipher suite in use and the server's X509 certificates, to |
| * application software which knows about this protocol handler. |
| * |
| * </UL> |
| * |
| * <P> System properties used include: <UL> |
| * |
| * <LI><em>https.proxyHost</em> ... the host supporting SSL |
| * tunneling using the conventional CONNECT syntax |
| * |
| * <LI><em>https.proxyPort</em> ... port to use on proxyHost |
| * |
| * <LI><em>https.cipherSuites</em> ... comma separated list of |
| * SSL cipher suite names to enable. |
| * |
| * <LI><em>http.nonProxyHosts</em> ... |
