EdgeRules: Add a Custom Header to Origin

Overview

You can use this document to apply a custom request header to the CDN requests for your origin server. 

This rule can be used to check for specific browsing habits or confirmation that a request was made by the CDN for troubleshooting purposes.

Step 1: Create a rule 

1. In the StackPath Control Portal, in the left-side navigation, click Sites. 
2. Locate and select the desired site. 
3. In the left-side navigation, click Edge Rules.
4. Click Edge Rules. 
5. Scroll down to Delivery Rules, and then click Add Delivery Rule. 
6. In Rule Name, enter a descriptive name for the rule.
7. Create and save the following EdgeRule:

   If	URL	Matches	*://Edge.Address/* Enter your own edge address or desired delivery domain.
   Then	Add Header To Origin Select the desired request header.	Header Enter the name of the header.	CDN Enter a value.

   
   

Note:

To apply this rule to different file types, prefix the rule with a question mark ( ? ) to indicate a wildcard location, and use a vertical bar ( | ) to separate each file type. 

For example, the following rule applies to PDF, HTML, JPG, JPEG, and GIT files: 
/\.(?.pdf|htm?l|jpe?g|gif)$/

Step 2: Verify the rule

This rule does not add any publicly accessible headers or redirects. As a result, to verify the rule, you will need to check the access logs on the origin server.

Please consult your hosting provider to learn how to view the access logs.
