Maximal number of concurrent connections per proxy server for WebSocket requests

Computer and userIntune-readyMaxConnectionsPerProxyForWebSocket

Supported on Microsoft Windows 7 or later

1.97.59

What it does

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 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. Setting a value above that limit will cause 256 to be used. Raise above the default (128) at your own risk. Please note that the enforced limits are impacted by AllowSocketPoolSizeRandomizationForProxies.

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
Option values are the template defaults, or sample values chosen from each option's type where the template has none; set your own values before deploying.
