/**
 * Implementation of {@link ChannelDecisionManager}.

Iterates through each configured {@link ChannelProcessor}. * If a ChannelProcessor has any issue with the security of the request, it should cause a redirect, * exception or whatever other action is appropriate for the ChannelProcessor implementation.

*

Once any response is committed (ie a redirect is written to the response object), the * ChannelDecisionManagerImpl will not iterate through any further ChannelProcessors.
