Overrides:

Throws:

requestEncoded

public void requestEncoded(org.jboss.netty.handler.codec.http.HttpRequest request)

Adds this HTTP request. We need to keep track of all encoded requests because we ultimately need the request data to determine whether or not we can cache responses. It's a queue because we're dealing with HTTP 1.1 persistent connections, and we need to match all requests with responses. NOTE that this is the original, unmodified request in this case without hop-by-hop headers stripped and without HTTP request filters applied. It's the raw request we received from the client connection. See ProxyHttpRequestEncoder.

Parameters:

request - The HTTP request to add.

channelWritable

public void channelWritable(org.jboss.netty.channel.ChannelHandlerContext ctx,
                   org.jboss.netty.channel.ChannelStateEvent cse)

Specified by:

channelWritable in interface InterestOpsListener
