Policies

Loon processes traffic in the following order:

Receive request → Match rule → Select policy → Choose node

A rule specifies a policy, and the policy determines the final node. A policy can be a node, a built-in policy, or a policy group.

Node policies

A rule can specify a node directly:

# The node name is "Hong Kong 01"
DOMAIN,google.com,Hong Kong 01

Connect to the destination directly without a proxy:

DOMAIN,apple.com,DIRECT

Reject policies are commonly used to block ads or unwanted requests:

Policy	Behavior
`REJECT`	Returns 404 with an empty response body
`REJECT-IMG`	Returns 200 with a 1×1 GIF
`REJECT-DICT`	Returns 200 with an empty JSON object
`REJECT-ARRAY`	Returns 200 with an empty JSON array
`REJECT-DROP`	Drops the request without returning a response

Some apps retry immediately after a connection failure. Use REJECT-DROP with care if this causes a request storm.
