nng_http_hijack - hijack HTTP server connection
nng_http_hijack() function hijacks the connection conn, causing it
to be disassociated from the HTTP server where it was created.
The purpose of this function is the creation of HTTP upgraders (such as WebSocket), where the underlying HTTP connection will be taken over for some other purpose, and should not be used any further by the server.
This function is most useful when called from a handler function.
It is the responsibility of the caller to dispose of the underlying
connection when it is no longer needed.
Furthermore, the HTTP server will no longer send any responses to the
hijacked connection, so the caller should do that as well if appropriate.
|This function is intended to facilitate uses cases that involve changing the protocol from HTTP, such as WebSocket. Most applications will never need to use this function.|
The connection was closed.
Insufficient free memory exists.
HTTP not supported.
