Rules Overview

Rules let you tell nsin how to handle visitors to your site. With a rule you can send people to a new page, change how caching works, slow down attackers, or block bad traffic — all without touching your server.

You create rules in the Rules section of your dashboard.

How a rule works

Every rule has two parts:

1. When — the condition that decides if the rule should run (for example, “when the address starts with /old-page”).
2. Then — the action to take (for example, “redirect to /new-page”).

If a visitor’s request matches the When, nsin does the Then.

The kinds of rules

Rule	What it does	Guide
Redirect	Send visitors from one address to another.	Redirects
Cache Rule	Change how a page is cached (or skip the cache).	Cache Rules
Rate Limiting	Slow down visitors who make too many requests.	Rate Limiting
WAF (Firewall)	Block harmful or unwanted traffic.	WAF

Create a rule

1. Open the Rules section.
2. Click Add Rule.
3. Pick the rule type.
4. Set the When condition.
5. Set the Then action.
6. Save.

The order of rules matters

Rules run from top to bottom. If two rules could match the same visitor, the one higher up runs first. You can drag rules to reorder them.

Tip

Put your most specific rules at the top and your general “catch-all” rules at the bottom.

Turning rules on and off

You don’t have to delete a rule to stop it. Use the toggle next to each rule to turn it off, then back on later if you need it.
