Domain Set
A Domain Set is a highly optimized remote configuration containing a large collection of domain rules. It is significantly more efficient than a standard Rule Set for large numbers of domain-based rules.
Compared to RULE-SET, a Domain Set only supports domain-type rules, but it offers significant performance improvements.
Example
Domain Set Definition
# Routes traffic matching domains in the remote ad-blocking list to REJECT
DOMAIN-SET,https://example.com/ad_domains.txt,REJECT
Remote Domain Set Content Example
www.apple.com
google.com
.google.com
Note that .google.com will match www.google.com as well as google.com.
Format
DOMAIN-SET, {domain set url}, {target}, update-interval = {update-interval}
Parameters
| Name | Value | Mandatory | Note |
|---|---|---|---|
| domain set url | - | true | |
| target | - | true | The specified proxy or proxy group must exist in the profile. |
| update-interval | seconds | false | Background refresh interval of the remote content, e.g. update-interval=86400. Minimum effective interval: 900 (15 minutes). Updated content applies the next time the VPN starts; a running VPN is not interrupted. When omitted, the content is only refreshed lazily when it is older than 24 hours. |
