Issue
Is it possible to add a custom header value to the image response?
Our company requires an "Access-Control: header in our images to enable cross-origin request support.
Solution
Implement a ruleset that uses the header tag. Here is an example:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE ruleset SYSTEM "RuleSet.dtd">
<ruleset>
<rule OnMatch="continue">
<expression>\$CORS=</expression>
<header Name="Access-Control-Allow-Origin">$CORS$</header>
</rule>
</ruleset>
