public abstract class CaptchaChannelProcessorTemplate

extends java.lang.Object

implements org.acegisecurity.securechannel.ChannelProcessor, org.springframework.beans.factory.InitializingBean

CaptchaChannel template : Ensures the user has enough human privileges by review of the CaptchaSecurityContext and using an abstract routine isContextValidConcerningHumanity(CaptchaSecurityContext) 55 (implemented by sub classes)

The component uses 2 main parameters for its configuration :

• a keyword to be mapped to urls in the org.acegisecurity.securechannel.ChannelProcessingFilter configuration
  default value provided by sub classes.
• and a thresold : used by the routine isContextValidConcerningHumanity(CaptchaSecurityContext) 55 to evaluate whether the CaptchaSecurityContext is valid default value = 0
