About Transform Rules
Transform Rules allow you to make adjustments to incoming requests at the edge before they go through any other Cloudflare products.
There are two types of Transform Rules:
URL Rewrite Rules:
- Rewrite the path of the URL of an HTTP request
- Rewrite the query string of the URL of an HTTP request
HTTP Request Header Modification Rules:
- Set the value of an HTTP request header
- Remove an HTTP request header
To configure Transform Rules in the dashboard, use the Transform Rules tab in Rules.
Cloudflare Transform Rules are available to all customers. Keep in mind that support for regular expressions is based on your plan type.
This table outlines the Transform Rules features available with each customer plan:
|Active Transform Rules||2||5||10||20|
