The OpenD Programming Language

RequestServer.listenSpec

The array of addresses you want to listen on. The format looks like a url but has a few differences.

This ONLY works on embedded_httpd_threads, embedded_httpd_hybrid, and scgi builds at this time.

http://localhost:8080

http://unix:filename/here

scgi://abstract:/name/here

http://[::1]:4444

Note that IPv6 addresses must be enclosed in brackets. If you want to listen on an interface called unix or abstract, contact me, that is not supported but I could add some kind of escape mechanism.

If you leave off the protocol, it assumes the default based on compile flags. If you only give a number, it is assumed to be a port on any tcp interface.

localhost:8080 serves the default protocol.

8080 or :8080 assumes default protocol on localhost.

The protocols can be http:, https:, and scgi:. Original cgi is not supported with this, since it is transactional with a single process.

Valid hosts are an IPv4 address (with a mandatory port), an IPv6 address (with a mandatory port), just a port alone, unix:/path/to/unix/socket (which may be a relative path without a leading slash), or abstract:/path/to/linux/abstract/namespace.

http://unix:foo will serve http over the unix domain socket named foo in the current working directory.

If you set this to anything non-null (including a non-null, zero-length array) any listenSpec entries, listeningHost and listeningPort are ignored.

Bugs

The implementation currently ignores the protocol spec in favor of the default compiled in option.
