Module: mod_wstunnel

EXPERIMENTAL (new in lighttpd 1.4.46)


Brief description of mod_wstunnel directives

option description
wstunnel.server backend server to which to send requests
wstunnel.balance load-balancing algorithm for backends ("fair", "least-connection", "round-robin", "hash", or "sticky")
wstunnel.debug debug level (value between 0 and 65535)
wstunnel.frame-type websocket frame type: "text" or "binary" map multiple extensions to the same wstunnel backend list of permitted origins in Origin request header (optional) send websocket PING frame at given interval in sec (default 0; none sent)
wstunnel.server-option description
host ip of the backend process
port tcp-port on the "host" used by the backend process
socket path to the unix-domain socket
bin-path path to the local backend binary which should be started if no local backend is running
bin-environment set environment of backend binary
bin-copy-environment copy environment from server for backend binary
disable-time time to wait before a disabled backend is checked again
idle-timeout number of seconds before a unused process gets terminated
listen-backlog listen backlog queue size (for backend daemons started by mod_wstunnel)
max-load-per-proc maximum number of waiting processes on average per process before a new process is spawned
max-procs upper limit of processes to start
min-procs sets the minimum processes to start

Details for wstunnel.server parameters can be found in mod_fastcgi documentation, since the wstunnel module shares the same code infrastructure with the FastCGI module, and fastcgi.server parameters are very similar.
