Origin-Pull URL Rewrite

Overview

When the client sends the request to the EdgeOne node, and the request fails to hit the node cache and needs to be returned to the origin, it supports the redirection of the request to the destination URL of the origin server according to the rules set by origin-pull URL rewrite. This feature does not affect the node cache.

Use cases

In certain cases, the URL accessed by the client has been published and should not be modified, but the origin server has changed its URL for certain reasons; or the URL accessed by the client differs from that on the origin server for SEO. Then, you can set origin-pull URL rewrite rules, so that the node can rewrite the origin-pull URL to the actual resource URL on the origin server without changing the URL accessed by the client.

Directions

Scenario: The client request URL is inconsistent with the corresponding origin server resource path

For example, when a client requests the URL path http://www.example.com/online/index.html from the site domain www.example.com, and the file directory has been changed, it is necessary to remove the directory prefix /online during the origin-pull to access the corresponding file resources. The following steps can be referred to:
1. Log in to the EdgeOne console, click Site List on the left sidebar, and click the Site to be configured in the site list.
2. On the site details page, click on the Rule Engine.
3. On the rule engine management page, click on Create rule, which will lead to the new rule editing page.
3.1. On the rule editing page, select the Matching type as HOST is www.example.com.
3.2. Click on Action, and in the pop-up action list, select the action as Rewrite origin-pull URL.
3.3. Select the Type as Remove path prefix, with the path prefix being /online, as configured below:



4. Click Save and Publish to complete the configuration.

The explanations for each configuration item of the origin-pull URL rewrite are as follows:
Type
Description
Add path prefix
Add the specified prefix to the request URL. For example, if the request URL is http://www.example.com/path0/index.html and the prefix to be added is /prefix, the rewritten URL will be http://www.example.com/prefix/path0/index.html.
Remove path prefix
Remove the specified prefix from the request URL. For example, if the request URL is http://www.example.com/path0/path1/index.html and the prefix to be removed is /path0, the rewritten URL will be http://www.example.com/path1/index.html.
Replace full path
Replace the complete request URL. For example, if the request URL is http://www.example.com/path0/index.html and the path to be replaced is /new/page.html, the rewritten URL will be http://www.example.com/new/page.html.
