Debug info in headers instead?

  • Is there any way you could attach the debug info using HTTP headers instead of an HTML comment, perhaps with an X-W3TC- prefix? For example:

    X-W3TC-Engine: disk: basic
    X-W3TC-Cache key: KEY

    ….

    Now that “application/json” is a supported content type (which, btw, is a fantastic new feature) the HTML comments no longer work well universally.
