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

Specifies the maximum number of simultaneous connections to a proxy server for WebSocket requests.

To configure limits for non-WebSocket requests, see the 'MaxConnectionsPerProxy' (Maximum number of concurrent connections to the proxy server for non-WebSocket requests) policy.

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

Some web applications maintain multiple concurrent connections, such as long-lived or hanging requests. Setting a value lower than the default can cause networking delays when many of these applications are open.

Some proxy servers can't handle a high number of concurrent connections per client. In these cases, reducing this value might improve reliability.

The supported range is 6 to 256:
- Values less than 6 are treated as 6.
- Values greater than 256 are treated as 256.

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 2x the value specified by this policy as a security mechanism.

We recommend modifying this value only if required by your proxy server configuration or network environment.
