Enables HTTP/0.9 support on non-default ports

This policy enables HTTP/0.9 on ports other than 80 for HTTP and 443 for HTTPS.

This policy is disabled by default, and if enabled, leaves users open to the security issue https://crbug.com/600352.

This policy is intended to give enterprises a chance to migrate exising servers off of HTTP/0.9, and will be removed in the future.

If this policy is not set, HTTP/0.9 will be disabled on non-default ports.
