Package com.zfabrik.util.microweb

Class MicroWebFilter

java.lang.Object

com.zfabrik.util.microweb.MicroWebFilter

All Implemented Interfaces:

javax.servlet.Filter

public class MicroWebFilter
extends Object
implements javax.servlet.Filter

All this filter does is to check wether an action should be executed for this request. If so, it will call the action. The outcome of that action determines where to go next. Actions are determined by the path information of the request URL. It will be cut into segments and actions will be applied according to a longest match pattern. The relevant URL can be obtained via MicroWebUtil#getRelevantPath(HttpServletRequest). Actions that require relative addressing in turn should send a redirect in case of a missing trailing "/"
