Class Filter

java.lang.Object

com.sun.net.httpserver.Filter

public abstract class Filter
extends Object

A filter used to pre- and post-process incoming requests. Pre-processing occurs before the application's exchange handler is invoked, and post-processing occurs after the exchange handler returns. Filters are organised in chains, and are associated with HttpContext instances.

Each Filter in the chain, invokes the next filter within its own doFilter(HttpExchange, Chain) implementation. The final Filter in the chain invokes the applications exchange handler.
