I’m trying to create a page rule for caching a non-static resource. But the request for this resource has an header that can vary. This header is custom; it has nothing to do with the usual HTTP cache headers.
I want the cache to have into account that header. Like if the header was part of the cache key. Is it possible to be done? I’m not being able to accomplish that.
I’m my page rule I’m using “Cache Level” setting with value “Cache Everything”. Shouldn’t this setting be sufficient for the cache to be sensitive to different values of custom headers?
