Java的.net.SecureCacheResponse类在Java中

Java的SecureCacheResponse类表示最初通过安全方式检索的缓存响应。

语法：类声明

public abstract class SecureCacheResponse
extends CacheResponse

这个类的构造函数如下

SecureCacheResponse()

现在，这个类的方法如下：

Method	Description
getCipherSuite()	This method is used to return the cipher suite in use on the original connection that retrieved the network resource.
getLocalCertificateChain()	This method is used to return the certificate chain that was sent to the server during handshaking of the original connection that retrieved the network resource.
getLocalPrincipal()	This method is used to return the principal that was sent to the server during handshaking in the original connection that retrieved the network resource.
getPeerPrincipal()	This method is used to return the server’s principal which was established as part of defining the session during the original connection that retrieved the network resource.
getServerCertificateChain()	This method is used to return the server’s certificate chain, which was established as part of defining the session in the original connection that retrieved the network resource, from the cache.
