Class HttpConnectorFactory

java.lang.Object

io.dropwizard.jetty.HttpConnectorFactory

All Implemented Interfaces:

io.dropwizard.jackson.Discoverable, ConnectorFactory

Direct Known Subclasses:

HttpsConnectorFactory

public class HttpConnectorFactory
extends Object
implements ConnectorFactory

Builds HTTP connectors.

Configuration Parameters:

Name	Default	Description
port	8080	The TCP/IP port on which to listen for incoming connections.
bindHost	(none)	The hostname to bind to.
inheritChannel	false	Whether this connector uses a channel inherited from the JVM. Use it with Server::Starter, to launch an instance of Jetty on demand.
headerCacheSize	512 bytes	The size of the header field cache.
outputBufferSize	32KiB	The size of the buffer into which response content is aggregated before being sent to the client. A larger buffer can improve performance by allowing a content producer to run without blocking, however larger buffers consume more memory and may induce some latency before a client starts processing the content.
maxRequestHeaderSize	8KiB	The maximum size of a request header. Larger headers will allow for more and/or larger cookies plus larger form content encoded in a URL. However, larger headers consume more memory and can make a server more vulnerable to denial of service attacks.
maxResponseHeaderSize	8KiB	The maximum size of a response header. Larger headers will allow for more and/or larger cookies and longer HTTP headers (eg for redirection). However, larger headers will also consume more memory.
inputBufferSize	8KiB	The size of the per-connection input buffer.
idleTimeout	30 seconds	The maximum idle time for a connection, which roughly translates to the Socket.setSoTimeout(int) call, although with NIO implementations other mechanisms may be used to implement the timeout. The max idle time is applied: When waiting for a new message to be received on a connection When waiting for a new message to be sent on a connection This value is interpreted as the maximum time between some progress being made on the connection. So if a single byte is read or written, then the timeout is reset.
blockingTimeout	(none)	The timeout applied to blocking operations. This timeout is in addition to the idleTimeout, and applies to the total operation (as opposed to the idle timeout that applies to the time no data is being sent).
minBufferPoolSize	64 bytes	The minimum size of the buffer pool.
bufferPoolIncrement	1KiB	The increment by which the buffer pool should be increased.
maxBufferPoolSize	64KiB	The maximum size of the buffer pool.
acceptorThreads	(Jetty's default)	The number of worker threads dedicated to accepting connections. By default is max(1, min(4, #CPUs/8)).
selectorThreads	(Jetty's default)	The number of worker threads dedicated to sending and receiving data. By default is max(1, min(4, #CPUs/2)).
acceptQueueSize	(OS default)	The size of the TCP/IP accept queue for the listening socket.
reuseAddress	true	Whether or not SO_REUSEADDR is enabled on the listening socket.
soLingerTime	(disabled)	Enable/disable SO_LINGER with the specified linger time.
useServerHeader	false	Whether or not to add the Server header to each response.
useDateHeader	true	Whether or not to add the Date header to each response.
useForwardedHeaders	true	Whether or not to look at X-Forwarded-* headers added by proxies. See ForwardedRequestCustomizer for details.
httpCompliance	RFC7230	This sets the http compliance level used by Jetty when parsing http, this can be useful when using a non-RFC7230 compliant front end, such as nginx, which can produce multi-line headers when forwarding client certificates using proxy_set_header X-SSL-CERT $ssl_client_cert; Possible values are set forth in the org.eclipse.jetty.http.HttpCompliance enum: RFC7230: Disallow header folding. RFC2616: Allow header folding.
