Class ErrorRedirectFilter

java.lang.Object
  org.jasig.cas.client.util.ErrorRedirectFilter

All Implemented Interfaces:

javax.servlet.Filter

public final class ErrorRedirectFilter
extends java.lang.Object
implements javax.servlet.Filter

Filters that redirects to the supplied url based on an exception. Exceptions and the urls are configured via init filter name/param values.

If there is an exact match the filter uses that value. If there's a non-exact match (i.e. inheritance), then the filter uses the last value that matched.

If there is no match it will redirect to a default error page. The default exception is configured via the "defaultErrorRedirectPage" property.
