 * Hi, does this work with caching plugins like WP Fastest Cache or WP Super Cache?
 * When i test headers at this site [https://securityheaders.io/](https://securityheaders.io/)
   with caching disabled it shows headers are working, but they don’t seem to work
   when caching is enabled? I’ve tried clearing cache but still same result.

 * You are right. In fact, it looks like numerous cache plug-ins are only caching
   the content of a page, not the http headers…
    From my tests, I found out that
   only W3 Total Cache does not remove these headers.

 * Hi Carl, after testing some other caching plugins i found that Comet Cache doesn’t
   strip the security headers. Works perfectly with that! Thanks

 * Hi
    This has to be a security issue, how many website owners on the internet 
   have web security in place then these caching plugins just strip out the headers
   so now their website is unsafe again.
 * I have tested my website using [https://observatory.mozilla.org/](https://observatory.mozilla.org/)
   and [https://securityheaders.io/](https://securityheaders.io/) and get inconsistent
   results.
 * On both websites I get a low score but disable the caching plugin and I get a
   high score. I thought I was doing it wrong.
