Class ThreadingFilter

java.lang.Object

org.eclnt.jsfserver.util.CCFilterBase

org.eclnt.jsfserver.util.ThreadingFilter

All Implemented Interfaces:

javax.servlet.Filter, ICCServerConstants, CLogConstants

public class ThreadingFilter
extends CCFilterBase
implements javax.servlet.Filter, CLogConstants, ICCServerConstants

Central filter that needs to be in front of the CaptainCasa server side processing. The main function is to serialize requests by their session id - so that within one session only one request is processed at a certain point of time. - Without this filter applications would have to deal with concurrent threads which is "a nightmare" for server side applications.
