Maximum number of concurrent connections to the proxy server for non-WebSocket requests

This policy configures the maximum number of simultaneous connections to a proxy server.

Some web applications maintain multiple long-lived connections, such as hanging GET requests. Setting this policy to a value lower than the default might cause browser networking issues when many of these applications are open.

To configure WebSocket request limits, use the 'MaxConnectionsPerProxyForWebSocket' (Maximum number of concurrent connections to the proxy server for WebSocket requests) policy.

If you don't configure this policy, the default value of 128 is used.

The value must be between 6 and 256:
- Values lower than 6 are treated as 6.
- Values higher than 256 are treated as 256. In Microsoft Edge version 148 and earlier, values higher than 99 are treated as 99.

When the 'AllowSocketPoolSizeRandomizationForProxies' (Allow socket pool size randomization for proxies) policy is enabled, which is the default, the effective upper limit can be randomized up to two times the value specified by this policy as a security mechanism.

We recommend changing this value from the default only when required by your proxy server configuration.
