Member Function Documentation

addHeader()

Result SC::HttpOutgoingMessage::addHeader	(	StringSpan	headerName,
		StringSpan	headerValue )

Writes an http header to this response.

Returns

Valid Result if header was added successfully.

Warning

Adding a "Connection" header can fail if keep-alive has been force disabled

end()

Result SC::HttpOutgoingMessage::end

(

)

Finalizes the writable stream after sending all in progress writes.

getKeepAlive()

bool SC::HttpOutgoingMessage::getKeepAlive ( ) const

inlinenodiscard

Gets whether the connection should be kept alive after this response.

Returns

true if connection should be kept alive

getWritableStream()

AsyncWritableStream & SC::HttpOutgoingMessage::getWritableStream ( )

inline

Obtain writable stream for sending content back to connected client.

reset()

void SC::HttpOutgoingMessage::reset

(

)

Resets this object for it to be re-usable.

sendHeaders()

Result SC::HttpOutgoingMessage::sendHeaders

(

Function< void(AsyncBufferView::ID)>

callback = {}

)

Start sending response headers, before sending any data.

setKeepAlive()

void SC::HttpOutgoingMessage::setKeepAlive

(

bool

keepAlive

)

Sets whether to keep the connection alive after this response.

Parameters

keepAlive

true to keep connection open for more requests, false to close after response

Warning

HttpConnection can force disable keep-alive when running out of connections to prevent server deadlock

Member Data Documentation

connectionHeaderAdded

bool SC::HttpOutgoingMessage::connectionHeaderAdded = false

protected

forceDisableKeepAlive

bool SC::HttpOutgoingMessage::forceDisableKeepAlive = false

protected

Whether keep alive has been force disabled permanently.

keepAlive

bool SC::HttpOutgoingMessage::keepAlive = true

protected

Whether to keep connection alive (HTTP/1.1 default)
