server/websocket/worker_threads

The number of available WebSocket worker threads.

Properties

Name	Type	Constraints	Description
max	number	Minimum: `0` Maximum: `unlimited` Default value: `0`	The maximum number of threads which will be used used to proxy WebSocket connections through the gateway. A value of zero will cause WebSockets to be blocked. Each WebSocket connection will require two worker threads. If more than the max value are in use, the daemon will immediately close the WebSocket even if the WebSocket upgrade request to the application succeeded. The WebSocket threads operate independently from the server:worker_threads entry.
idle	number	Minimum: `0` Maximum: `unlimited` Default value: `0`	To avoid the overhead of starting and stopping web socket worker threads a number of threads can be left running idle. This will consume memory resources to keep them alive and idle when not in use, but will save CPU and thread start-up time when a new web socket requires threads. This option specifies the maximum count of cached idle worker threads. A value of zero will disable the caching of idle threads.

server/websocket/timeouts

Web socket timeout settings.

server/websocket/timeouts/applications

Specifies the web socket timeouts for connections between the gateway daemon and protected applications (in seconds). If the timeout is reached the web socket connection will be closed.

Properties

Name	Type	Constraints	Description
read	number	Minimum: `1` Maximum: `unlimited` Default value: `120`	The maximum length of time (in seconds) to wait on a read operation to complete.
write	number	Minimum: `1` Maximum: `unlimited` Default value: `20`	The maximum length of time (in seconds) to wait on a write operation to complete.

server/websocket/timeouts/front_end

Specifies the web socket timeouts for connections to the gateway (in seconds). If the timeout is reached the web socket connection will be closed.

Properties

Name	Type	Constraints	Description
read	number	Minimum: `1` Maximum: `unlimited` Default value: `120`	The maximum length of time (in seconds) to wait on a read operation to complete.
write	number	Minimum: `1` Maximum: `unlimited` Default value: `20`	The maximum length of time (in seconds) to wait on a write operation to complete.
