Class AbstractRewriteFilter
java.lang.Object
com.caucho.rewrite.AbstractRewriteFilter
- All Implemented Interfaces:
- RewriteFilter
- Direct Known Subclasses:
- AddHeader, SetHeader, SetRequestSecure, SetVary
public abstract class AbstractRewriteFilter
- extends java.lang.Object
- implements RewriteFilter
Implements general extended behavior for rewrite filters like
resin:SetHeader. RewriteFilters act like standard servlet filters,
but are configured using Resin's rewrite syntax.
- regexp
- predicates
- sub-rewrite-filters
- sub-servlet-filters
Abstract filters have a URL regexp pattern which only
applies the filter to matching URLs. If the regexp is missing, all
URLs will match.
Any rewrite/security predicate like IfUser or IfAddress can be used
to restrict requests. Only requests that match all the predicates will
be filtered.
The AbstractRewriteFilter can have child RewriteFilters and child
servlet Filters. The children will only be added to the filter chain if
the predicates match.
