Maximal number of concurrent connections per proxy server for WebSocket requests
Last updated March 31, 2026
Setting the policy specifies the maximal number of simultaneous connections per proxy server for WebSocket requests.
To modify non-WebSocket request limits, see MaxConnectionsPerProxy.
Leaving the policy unset means a default of 32 is used.
Some web apps are known to consume many connections with hanging GETs, so setting a value below 32 may lead to browser networking hangs if there are too many web apps with hanging connections open.
Some proxy servers can't handle a high number of concurrent connections per client, which is solved by setting this policy to a lower value.
The value should be equal to or higher than 6.
Setting a value below that limit will cause 6 to be used.
Lower below the default (32) at your own risk.
The value should be equal to or lower than 256.
Setting a value above that limit will cause 256 to be used.
Raise above the default (32) at your own risk.
