Class RedirectFilter

java.lang.Object
  org.apache.tapestry.RedirectFilter

All Implemented Interfaces:

Filter

public class RedirectFilter
extends Object
implements Filter

Filter used to redirect a root context URL (i.e., "/context" or "/context/" to the Tapestry application servlet (typically, "/context/app"). This servlet is mapped to "/" and must have a <init-parameter&;gt; redirect-path that is the application servlet's path (i.e., "/app"). If no value is specified, then "/app" is used. The path is always relative to the servlet context, and should always begin with a leading slash.

Filters are only available in Servlet API 2.3 and above.

Servlet API 2.4 is expected to allow a servlets in the welcome list (equivalent to index.html or index.jsp), at which point this filter should no longer be necessary.

Since:

3.0

This code is interested in only the very root, redirecting to the appropriate Tapestry application servlet. Other values are passed through unchanged.
