Inherits: SocketAdapter

HTTP server implementation.

This HTTP server is not strictly standards compliant. It was created to be a fast (nocopy where possible) solution for streaming media to web browsers.

Public Attributes

Return	Name	Description
`LocalSignal< void(ServerConnection::Ptr)>`	`Connection`	Signals when a new connection has been created. A reference to the new connection object is provided.
`LocalSignal< void()>`	`Shutdown`	Signals when the server is shutting down.

Connection

LocalSignal< void(ServerConnection::Ptr)> Connection

Signals when a new connection has been created. A reference to the new connection object is provided.

Shutdown

LocalSignal< void()> Shutdown

Signals when the server is shutting down.

Public Methods

Return	Name	Description
	`Server`	Constructs an HTTP server on the given host and port using an internally created TCP socket.
	`Server`	Constructs an HTTP server on the given address using an internally created TCP socket.
	`Server`	Constructs an HTTP server on the given host and port using a caller-supplied socket. Useful for HTTPS by passing an SSLSocket. The event loop is derived from the socket.
	`Server`	Constructs an HTTP server on the given address using a caller-supplied socket. The event loop is derived from the socket.
`void`	`start`	Start the HTTP server.
`void`	`stop`	Stop the HTTP server.
`void`	`setReusePort` `inline`	Enable SO_REUSEPORT for multicore server instances. Must be called before start(). Allows multiple server instances to bind the same address:port with kernel-level load balancing (Linux 3.9+).
`void`	`setMaxPooledConnections` `inline`	Set the maximum number of pooled connections (default 128). Set to 0 to disable connection pooling entirely.
`void`	`setKeepAliveTimeout` `inline`	Set the keep-alive idle timeout in seconds (default 30). Connections idle longer than this are closed by the timer. Set to 0 to disable idle timeout.
`size_t`	`connectionCount` `const` `inline`	Return the number of active connections (all states).
`net::Address &`	`address`	Return the server bind address.
`const DateCache &`	`dateCache` `const` `inline`	Return the cached Date header for use in responses.

Server

Server(const std::string & host, short port, uv::Loop * loop, std::unique_ptr< ServerConnectionFactory > factory)

Constructs an HTTP server on the given host and port using an internally created TCP socket.

Parameters

host Bind address (e.g. "0.0.0.0" or "127.0.0.1").
port TCP port to listen on.
loop Event loop to use. Defaults to the default libuv loop.
factory Connection and responder factory. Defaults to the base factory.

Server

Server(const net::Address & address, uv::Loop * loop, std::unique_ptr< ServerConnectionFactory > factory)

Constructs an HTTP server on the given address using an internally created TCP socket.

Parameters

address Bind address and port.
loop Event loop to use. Defaults to the default libuv loop.
factory Connection and responder factory.

Server

Server(const std::string & host, short port, net::TCPSocket::Ptr socket, std::unique_ptr< ServerConnectionFactory > factory)

Constructs an HTTP server on the given host and port using a caller-supplied socket. Useful for HTTPS by passing an SSLSocket. The event loop is derived from the socket.

Parameters

host Bind address.
port TCP port to listen on.
socket Pre-created socket (e.g. SSLSocket for HTTPS).
factory Connection and responder factory.

Server

Server(const net::Address & address, net::TCPSocket::Ptr socket, std::unique_ptr< ServerConnectionFactory > factory)

Constructs an HTTP server on the given address using a caller-supplied socket. The event loop is derived from the socket.

Parameters

address Bind address and port.
socket Pre-created socket (e.g. SSLSocket for HTTPS).
factory Connection and responder factory.

start

void start()

Start the HTTP server.

stop

void stop()

Stop the HTTP server.

setReusePort

inline

inline void setReusePort(bool enable)

Enable SO_REUSEPORT for multicore server instances. Must be called before start(). Allows multiple server instances to bind the same address:port with kernel-level load balancing (Linux 3.9+).

setMaxPooledConnections

inline

inline void setMaxPooledConnections(size_t n)

Set the maximum number of pooled connections (default 128). Set to 0 to disable connection pooling entirely.

setKeepAliveTimeout

inline

inline void setKeepAliveTimeout(int seconds)

Set the keep-alive idle timeout in seconds (default 30). Connections idle longer than this are closed by the timer. Set to 0 to disable idle timeout.

connectionCount

const inline

inline size_t connectionCount() const

Return the number of active connections (all states).

address

net::Address & address()

Return the server bind address.

dateCache

const inline

inline const DateCache & dateCache() const

Return the cached Date header for use in responses.
