Class RedirectFilter

java.lang.Object

org.pageseeder.berlioz.servlet.RedirectFilter

All Implemented Interfaces:

Serializable, javax.servlet.Filter

public final class RedirectFilter
extends Object
implements javax.servlet.Filter, Serializable

A basic filter to redirect URI patterns to other URI patterns.

The redirect mapping can be specified as below:

 <?xml version="1.0" encoding="utf-8"?>
 <redirect-mapping>
   <redirect from="/"             to="/html/home"/>
   <redirect from="/index.html"   to="/html/home"/>
   <redirect from="/html"         to="/html/home"/>
   <redirect from="/xml"          to="/xml/home"/>
   <redirect from="/{+path}.psml" to="/html/{+path}"/>
 </redirect-mapping>
 

All redirects are currently temporary (302) unless the attribute 'permanent' is set to 'yes' in which case the HTTP code will be 301

See #init(javax.servlet.ServletConfig) for details for configuration options.
