Edge Security Acceleration:Transform rules

Features overview

You can create transform rules to configure the features listed in the following table and apply the rules to requests that match a custom filter expression.

• Rewrite URLs

  If the storage path of your origin resources changes but you want to maintain the URL path that users access, you can rewrite URLs on Edge Security Acceleration (ESA) nodes. This allows you to modify the path and query string (request parameters) in the URL when user requests need to be forwarded to the origin, and use the rewritten URL to request resources from the origin.

• Modify request headers

  HTTP request headers are components of the header section in requests transmitted over HTTP. HTTP request headers provide specific parameters to servers. You can add, remove, modify, and replace HTTP headers in origin requests to meet various business requirements.

• Modify response headers

  An HTTP response header is part of an HTTP response message and carries specific response parameters to pass to clients. By configuring HTTP response headers, Edge Security Acceleration (ESA) nodes include the configured response headers in the response messages when returning resources to clients. This allows you to implement specific features such as cross-origin access.

• Add the "ali-real-client-ip" header

  You can use the managed transforms feature of Edge Security Acceleration (ESA) to apply common adjustments to HTTP request and response headers.
