 * Hi,
 * I think one or more nonces used in one of my plugins (Unipixel) are causing me
   problems.
    This plugin has stopped using jQuery and seems to rely more on AJAX.
   As a result, I’m now getting 403 errors on admin-ajax.php.
 * In theory, at the very least, the `ajax-nonce` should be excluded from the cache.
 * I think this is an issue with cached nonces, since the problem doesn’t appear
   immediately.
 * Unfortunately, I CAN’T enable ESI because the ASTRA Pro plugin isn’t compatible
   with ESI.
 * Is there a way to prevent all Unipixel nonces (and ajax-nonce) from being cached?
   Without using ESI, of course… otherwise, the site won’t work anymore.
 * Thanks ever so much for any advice.
    Best regards

 * well , if no ESI , then you have 2 possible option :
 * first , reduce the cache TTL , and schedule a purge twice per day to clear cache
   when nonce regenerates
 * second , extend the nonce token life.

 * Hi Qtwrk,
 * Ok, I’m going to try the first solution, since extending the lifetime of nonces
   isn’t recommended for security reasons.
 * Thank you all for your advice.
    Best regards
