mod_wstunnel¶
- Table of contents
- mod_wstunnel
Module: mod_wstunnel
WebSocket tunnel endpoint. This module terminates the websocket tunnel from a client. This module then passes data (without websocket frames) to a backend and encodes responses from backend in websocket frames before sending responses to client.
EXPERIMENTAL (new in lighttpd 1.4.46)
Note: if looking to proxy websockets to a backend, then see Docs_ModProxy, Docs_ModCGI, or other backends, some of which can be enabled to be transparent proxies to backends after client sends Upgrade: websocket
Description¶
Brief description of mod_wstunnel directives
| option | description |
|---|---|
| wstunnel.server | backend server definition(s) for hosts to which to send requests; options for each backend host |
| 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" |
| wstunnel.map-extensions | map multiple extensions to the same backend |
| wstunnel.origins | list of permitted origins in Origin request header (optional) |
| wstunnel.ping-interval | send websocket PING frame at given interval in sec (default 0; none sent) |
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.
