Class FrameworkFilter

java.lang.Object
  org.mmbase.framework.FrameworkFilter

All Implemented Interfaces:

Filter

public class FrameworkFilter
extends Object
implements Filter

Requestfilter that filters out all URL's looking for virtual 'userfriendly' links that have a corresponding page (technical URL) within the website. When the recieved URL is not recognized by the framework as an 'userfriendly' one, it just gets forwarded in its original form. The filtering and conversion to an URL pointing to an existing JSP template is done by an UrlConverter. Regular expressions that define URL's to be excluded from filtering should be listed in the 'excludes' parameter in web.xml.
