public class HttpServerFilter
extends HttpCodecFilter

Server side HttpCodecFilter implementation, which is responsible for decoding HttpRequestPacket and encoding HttpResponsePacket messages. This Filter is usually used, when we build an asynchronous HTTP server connection.

HttpServerFilter

public HttpServerFilter()

Constructor, which creates HttpServerFilter instance

HttpServerFilter

public HttpServerFilter(boolean chunkingEnabled,
                        int maxHeadersSize,
                        KeepAlive keepAlive,
                        DelayedExecutor executor)

Constructor, which creates HttpServerFilter instance, with the specific max header size parameter.

Parameters:

maxHeadersSize - the maximum size of the HTTP message header.

HttpServerFilter

public HttpServerFilter(Boolean isSecure,
                        boolean chunkingEnabled,
                        int maxHeadersSize,
                        KeepAlive keepAlive,
                        DelayedExecutor executor)

Constructor, which creates HttpServerFilter instance, with the specific max header size parameter.

Parameters:

isSecure - true, if the Filter will be used for secured HTTPS communication, or false otherwise. It's possible to pass null, in this case Filter will try to autodetect security.

maxHeadersSize - the maximum size of the HTTP message header.

Method Detail

handleRead

public NextAction handleRead(FilterChainContext ctx)
                      throws IOException

The method is called, once we have received a Buffer, which has to be transformed into HTTP request packet part. Filter gets Buffer, which represents a part or complete HTTP request message. As the result of "read" transformation - we will get HttpContent message, which will represent HTTP request packet content (might be zero length content) and reference to a HttpHeader, which contains HTTP request message header.

Specified by:

handleRead in interface Filter

Overrides:

handleRead in class BaseFilter

Parameters:

ctx - Request processing context

Returns:

NextAction

Throws:

IOException

handleEvent

public NextAction handleEvent(FilterChainContext ctx,
                              Object event)
                       throws IOException

Specified by:

handleEvent in interface Filter

Overrides:

handleEvent in class BaseFilter

Throws:

IOException

encodeHttpPacket

protected Buffer encodeHttpPacket(Connection connection,
                                  HttpPacket input)

Overrides:

encodeHttpPacket in class HttpCodecFilter

customizeErrorResponse

protected HttpContent customizeErrorResponse(HttpResponsePacket response)
