org.springframework.security.web.access.channel
Class SecureChannelProcessor

java.lang.Object
  extended by org.springframework.security.web.access.channel.SecureChannelProcessor
All Implemented Interfaces:
InitializingBean, ChannelProcessor

public class SecureChannelProcessor
extends Object
implements InitializingBean, ChannelProcessor

Ensures channel security is active by review of HttpServletRequest.isSecure() responses.

The class responds to one case-sensitive keyword, getSecureKeyword(). If this keyword is detected, HttpServletRequest.isSecure() is used to determine the channel security offered. If channel security is not present, the configured ChannelEntryPoint is called. By default the entry point is RetryWithHttpsEntryPoint.

The default secureKeyword is REQUIRES_SECURE_CHANNEL.
