### Returns

| [bool](https://learn.microsoft.com/dotnet/api/system.boolean) |             |

### Remarks

Socket connections attempted in a webplayer need to be validated by a socket policy. When the policy is hosted on a port different than the default port number (843) it needs to be explicitly fetched with this API call before any socket connections are attempted. The timeout argument is in milliseconds.

The return value indicates if a policy was successfully retrieved or not.

Note that web player is not supported from 5.4.0.
