Maximal number of concurrent connections per proxy server for non-WebSocket requests

What it does

Setting the policy specifies the maximal number of simultaneous connections per proxy server for non-WebSocket requests. To modify WebSocket request limits, see MaxConnectionsPerProxyForWebSocket. Leaving the policy unset means a default of 128 is used. Some web apps are known to consume many connections with hanging GETs, so setting a value below 128 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 (128) at your own risk. The value should be equal to or lower than 256 (99 in Brave 147 and earlier). Setting a value above that limit will cause 256 (99 in Brave 147 and earlier) to be used. Raise above the default (128) at your own risk. Please note that the enforced limits are impacted by AllowSocketPoolSizeRandomizationForProxies.
