Need help reading ancillary messages from unix domain socket

[prerak jain]

I have a server which needs to run multiple process on 443 port, for that I have a proxy server which will actually listen on 443 port and based on the TLS Client Hello server name(SNI) field it forwards the socket fds to the respective process using unix domain socket ancillary messages. Is there any way in nodejs where I can fetch the socket fd from the ancillary message and create connection using it.

Thanks Sam for the response, but in my case the proxy server forwarding the socket fd and the nodejs are two separate processes. The apis in link you mentioned can only be used if the processes has parent-child relationship.

You would have to write a binding to do that since support for it in core was removed post-node v0.4 I think? There are a couple of small libraries[1][2] that might make it a bit easier.
