AllowInsecureConnection- This setting controls whether or not the server will only accept https:// connections, or if it will accept both http:// and https:// connections. By default, this setting is set to false.
To only allow https:// connections to the server, this setting should be set to false.
To allow both http:// and https:// connections to the server, this setting should be set to true.
Note:
If AllowInsecureConnection is set to false, then the server must be correctly configured for HTTPS connections.
In the Web Application Management Console, this setting is available on the DeficiencyPop tab as Allow Insecure Connections.
